+#########################################################################
+# The boost threading library can be built on top of different API's
+# Currently this is the win32 API and the pthreads API.
+# Pthread is native on unix variants.
+# To get pthread on windows you need the pthread win32 library
+# http://sourceware.org/pthreads-win32 which is available under LGPL.
+#
+# You need to provide the include path and lib path in the variables
+# PTW32_INCLUDE and PTW32_LIB respectively. You can specify these
+# paths in site-config.jam, user-config.jam or in the environment.
+# A new feature is provided to request a specific API:
+# <threadapi>win32 and <threadapi)pthread.
+#
+# The naming of the resulting libraries is mostly the same for the
+# variant native to the build platform, i.e.
+# boost_thread and the boost specific tagging.
+# For the library variant that is not native on the build platform
+# an additional tag is applied:
+# boost_thread_pthread for the pthread variant on windows, and
+# boost_thread_win32 for the win32 variant (likely when built on cygwin).
+#
+# To request the pthread variant on windows, from boost root you would
+# say e.g:
+# bjam msvc-8.0 --with-thread install threadapi=pthread

+
+The original implementation of __boost_thread__ was written by William Kempf, with contributions from numerous others. This new
+version initially grew out of an attempt to rewrite __boost_thread__ to William Kempf's design with fresh code that could be
+released under the Boost Software License. However, as the C++ Standards committee have been actively discussing standardizing a
+thread library for C++, this library has evolved to reflect the proposals, whilst retaining as much backwards-compatibility as
+possible.
+
+Particular thanks must be given to Roland Schwarz, who contributed a lot of time and code to the original __boost_thread__ library,
+and who has been actively involved with the rewrite. The scheme for dividing the platform-specific implementations into separate

+[section:barriers Barriers]
+
+A barrier is a simple concept. Also known as a ['rendezvous], it is a synchronization point between multiple threads. The barrier is
+configured for a particular number of threads (`n`), and as threads reach the barrier they must wait until all `n` threads have
+arrived. Once the `n`-th thread has reached the barrier, all the waiting threads can proceed, and the barrier is reset.
+
+[section:barrier Class `barrier`]

+These deprecated features will be provided by default up to boost 1.52. If you don't want to include the deprecated features you could define BOOST_THREAD_DONT_PROVIDE_DEPRECATED_FEATURES_SINCE_V3_0_0. Since 1.53 these features will not be included any more by default. Since this version, if you want to include the deprecated features yet you could define BOOST_THREAD_PROVIDE_DEPRECATED_FEATURES_SINCE_V3_0_0. These deprecated features will be only available until boost 1.55, that is you have yet 1 year to move to the new features.

+
+Breaking changes when BOOST_THREAD_VERSION==3 (Default value since Boost 1.53):

+[heading Version 2.1.0 - Changes since boost 1.40]
+
+The 1.41.0 release of Boost adds futures to the thread library. There are also a few minor changes.
+
+[heading Changes since boost 1.35]
+
+The 1.36.0 release of Boost includes a few new features in the thread library:
+
+* New generic __lock_multiple_ref__ and __try_lock_multiple_ref__ functions for locking multiple mutexes at once.
+
+* Rvalue reference support for move semantics where the compilers supports it.
+
+* A few bugs fixed and missing functions added (including the serious win32 condition variable bug).
+
+* `scoped_try_lock` types are now backwards-compatible with Boost 1.34.0 and previous releases.
+
+* Support for passing function arguments to the thread function by supplying additional arguments to the __thread__ constructor.
+
+* Backwards-compatibility overloads added for `timed_lock` and `timed_wait` functions to allow use of `xtime` for timeouts.
+
+[heading Version 2.0.0 - Changes since boost 1.34]
+
+Almost every line of code in __boost_thread__ has been changed since the 1.34 release of boost. However, most of the interface
+changes have been extensions, so the new code is largely backwards-compatible with the old code. The new features and breaking
+changes are described below.
+
+[heading New Features]
+
+* Instances of __thread__ and of the various lock types are now movable.
+
+* Threads can be interrupted at __interruption_points__.
+
+* Condition variables can now be used with any type that implements the __lockable_concept__, through the use of
+`boost::condition_variable_any` (`boost::condition` is a `typedef` to `boost::condition_variable_any`, provided for backwards
+compatibility). `boost::condition_variable` is provided as an optimization, and will only work with
+`boost::unique_lock<boost::mutex>` (`boost::mutex::scoped_lock`).
+
+* Thread IDs are separated from __thread__, so a thread can obtain it's own ID (using `boost::this_thread::get_id()`), and IDs can
+be used as keys in associative containers, as they have the full set of comparison operators.
+
+* Timeouts are now implemented using the Boost DateTime library, through a typedef `boost::system_time` for absolute timeouts, and
+with support for relative timeouts in many cases. `boost::xtime` is supported for backwards compatibility only.
+
+* Locks are implemented as publicly accessible templates `boost::lock_guard`, `boost::unique_lock`, `boost::shared_lock`, and
+`boost::upgrade_lock`, which are templated on the type of the mutex. The __lockable_concept__ has been extended to include publicly
+available __lock_ref__ and __unlock_ref__ member functions, which are used by the lock types.
+
+[heading Breaking Changes]
+
+The list below should cover all changes to the public interface which break backwards compatibility.
+
+* __try_mutex__ has been removed, and the functionality subsumed into __mutex__. __try_mutex__ is left as a `typedef`,
+but is no longer a separate class.
+
+* __recursive_try_mutex__ has been removed, and the functionality subsumed into
+__recursive_mutex__. __recursive_try_mutex__ is left as a `typedef`, but is no longer a separate class.
+
+* `boost::detail::thread::lock_ops` has been removed. Code that relies on the `lock_ops` implementation detail will no longer work,
+as this has been removed, as it is no longer necessary now that mutex types now have public __lock_ref__ and __unlock_ref__ member
+functions.
+
+* `scoped_lock` constructors with a second parameter of type `bool` are no longer provided. With previous boost releases,
+``boost::mutex::scoped_lock some_lock(some_mutex,false);`` could be used to create a lock object that was associated with a mutex,
+but did not lock it on construction. This facility has now been replaced with the constructor that takes a
+`boost::defer_lock_type` as the second parameter: ``boost::mutex::scoped_lock some_lock(some_mutex,boost::defer_lock);``
+
+* The `locked()` member function of the `scoped_lock` types has been renamed to __owns_lock_ref__.
+
+* You can no longer obtain a __thread__ instance representing the current thread: a default-constructed __thread__ object is not
+associated with any thread. The only use for such a thread object was to support the comparison operators: this functionality has
+been moved to __thread_id__.
+
+* The broken `boost::read_write_mutex` has been replaced with __shared_mutex__.
+
+* __mutex__ is now never recursive. For Boost releases prior to 1.35 __mutex__ was recursive on Windows and not on POSIX platforms.
+
+* When using a __recursive_mutex__ with a call to [cond_any_wait_link `boost::condition_variable_any::wait()`], the mutex is only
+  unlocked one level, and not completely. This prior behaviour was not guaranteed and did not feature in the tests.
+
+[endsect]
+
+[section:future Future]
+
+The following features will be included in next releases. 
+
+# Complete the C++11 missing features, in particular
+  * [@http://svn.boost.org/trac/boost/ticket/7285 #7285] C++11 compliance: Allow to pass movable arguments for call_once. 
+  * [@http://svn.boost.org/trac/boost/ticket/6227 #6227] C++11 compliance: Use of variadic templates on Generic Locking Algorithms on compilers providing them. 
+
+
+# Add some of the extension proposed in [@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3428.pdf A Standardized Representation of Asynchronous Operations], in particular
+
+  * [@http://svn.boost.org/trac/boost/ticket/7589 #7589] Synchro: Add polymorphic lockables.
+  * [@http://svn.boost.org/trac/boost/ticket/7449 #7449] Synchro: Add a synchronized value class.
+  * [@http://svn.boost.org/trac/boost/ticket/7445 #7445] Async: Add future<>.then.

-
-        <p>An object of class <code>condition</code> is a synchronization
-        primitive used to cause a thread to wait until a particular shared-data
-        condition (or time) is met. A <code>condition</code> object is always
-        used in conjunction with a mutex object modeling a <a href=
-        "mutex_concept.html">Mutex Concept</a>. The mutex must be locked prior
-        to waiting on the <code>condition</code>, which is ensured by passing a
-        lock object modeling a <a href="lock_concept.html">Lock Concept</a> to
-        the <code>condition</code> object&#39;s <code>wait</code> functions.
-        While the thread is waiting on the <code>condition</code> object, the
-        mutex associated with the lock is unlocked. When the thread returns
-        from a call to one of the <code>condition</code> object&#39;s <code>
-        wait</code> functions, the mutex is again locked. The tricky
-        lock/unlock/lock sequence is performed automatically by the <code>
-        condition</code> object&#39;s <code>wait</code> functions.</p>
-
-        <p>The <code>condition</code> type is often used to implement the <i>
-        Monitor Object</i> and other important patterns. See <a href=
-        "bibliography.html#Schmidt-00">[Schmidt-00]</a> and <a href=
-        "bibliography.html#Hoare-74">[Hoare 74]</a>. Monitors are one of the
-        most important patterns for creating reliable multithreaded
-        programs.</p>
-
-        <p>See <a href="definitions.html">Formal Definitions</a> for
-        definitions of thread states <a href="definitions.html#state">
-        blocked</a> and <a href="definitions.html#state">ready</a>. Note that
-        &quot;waiting&quot; is a synonym for blocked.</p>

+[section:condvar_ref Condition Variables]
+
+[heading Synopsis]
+
+  namespace boost 
+  {
+    enum class cv_status;
+    {
+      no_timeout,
+      timeout
+    };
+    class condition_variable;
+    class condition_variable_any;
+    void notify_all_at_thread_exit(condition_variable& cond, unique_lock<mutex> lk);
+  }
+
+The classes `condition_variable` and `condition_variable_any` provide a
+mechanism for one thread to wait for notification from another thread that a
+particular condition has become true. The general usage pattern is that one
+thread locks a mutex and then calls `wait` on an instance of
+`condition_variable` or `condition_variable_any`. When the thread is woken from
+the wait, then it checks to see if the appropriate condition is now true, and
+continues if so. If the condition is not true, then the thread then calls `wait`
+again to resume waiting. In the simplest case, this condition is just a boolean
+variable:
+
+    boost::condition_variable cond;
+    boost::mutex mut;
+    bool data_ready;
+
+    void process_data();
+
+    void wait_for_data_to_process()
+    {
+        boost::unique_lock<boost::mutex> lock(mut);
+        while(!data_ready)
+        {
+            cond.wait(lock);
+        }
+        process_data();
+    }
+
+Notice that the `lock` is passed to `wait`: `wait` will atomically add the
+thread to the set of threads waiting on the condition variable, and unlock the
+mutex. When the thread is woken, the mutex will be locked again before the call
+to `wait` returns. This allows other threads to acquire the mutex in order to
+update the shared data, and ensures that the data associated with the condition
+is correctly synchronized.
+
+In the mean time, another thread sets the condition to `true`, and then calls
+either `notify_one` or `notify_all` on the condition variable to wake one
+waiting thread or all the waiting threads respectively.
+
+    void retrieve_data();
+    void prepare_data();
+
+    void prepare_data_for_processing()
+    {
+        retrieve_data();
+        prepare_data();
+        {
+            boost::lock_guard<boost::mutex> lock(mut);
+            data_ready=true;
+        }
+        cond.notify_one();
+    }
+
+Note that the same mutex is locked before the shared data is updated, but that
+the mutex does not have to be locked across the call to `notify_one`.
+
+This example uses an object of type `condition_variable`, but would work just as
+well with an object of type `condition_variable_any`: `condition_variable_any`
+is more general, and will work with any kind of lock or mutex, whereas
+`condition_variable` requires that the lock passed to `wait` is an instance of
+`boost::unique_lock<boost::mutex>`. This enables `condition_variable` to make
+optimizations in some cases, based on the knowledge of the mutex type;
+`condition_variable_any` typically has a more complex implementation than
+`condition_variable`.

+
+* __sleep__
+* __timed_join__
+* __cond_timed_wait__
+* __timed_lock_ref__
+
+
+When `BOOST_THREAD_VERSION<=3` define `BOOST_THREAD_DONT_USE_DATETIME ` if you don't want to use Boost.DateTime related interfaces.
+When `BOOST_THREAD_VERSION>3` define `BOOST_THREAD_USES_DATETIME ` if you want to use Boost.DateTime related interfaces.

+* `boost::thread::oprator!=`
+
+When `BOOST_THREAD_PROVIDES_THREAD_EQ` is defined Boost.Thread provides these deprecated feature. 
+

+
+* `boost::thread::id::oprator==`
+* `boost::thread::id::oprator!=`
+
+[warning This is a breaking change respect to version 1.x.]

+Boost.Threads includes in version 3 the Shared Locking Upwards Conversion as defined in [@http://home.roadrunner.com/~hinnant/bloomington/shared_mutex.html Shared Locking].
+These conversions need to be used carefully to avoid deadlock or livelock. The user need to define explicitly `BOOST_THREAD_PROVIDES_SHARED_MUTEX_UPWARDS_CONVERSION` to get these upwards conversions.

+
+C++11 uses `std::future`. Versions of Boost.Thread previous to version 3.0.0 uses `boost:unique_future`.
+Since version 3.0.0 `boost::future` replaces `boost::unique_future` when `BOOST_THREAD_PROVIDES_FUTURE` is defined. The documentation doesn't contains anymore however `boost::unique_future`.

-        <h2>Introduction</h2>
-
-        <p>The definitions are given in terms of the <a href=
-        "bibliography.html#ISO-98">C++ Standard</a>. References to the standard
-        are in the form [1.2.3/4], which represents the section number, with
-        the paragraph number following the &quot;/&quot;.</p>
-
-        <p>Because the definitions are written in something akin to
-        &quot;standardese&quot;, they can be difficult to understand. The
-        intent isn&#39;t to confuse, but rather to clarify the additional
-        requirements Boost.Threads places on a C++ implementation as defined by
-        the C++ Standard.</p>
-
-        <h2>Definitions</h2>
-
-        <h3>Thread</h3>
-
-        <p>Thread is short for &quot;thread of execution&quot;. A thread of
-        execution is an execution environment [1.9/7] within the execution
-        environment of a C++ program [1.9]. The main() function [3.6.1] of the
-        program is the initial function of the initial thread. A program in a
-        multi-threading environment always has an initial thread even if the
-        program explicitly creates no additional threads.</p>
-
-        <p>Unless otherwise specified, each thread shares all aspects of its
-        execution environment with other threads in the program. Shared aspects
-        of the execution environment include, but are not limited to, the
-        following:</p>
-
-        <ul>
-            <li>Static storage duration (static, extern) objects [3.7.1].</li>
-        </ul>
-
-        <ul>
-            <li>Dynamic storage duration (heap) objects [3.7.3]. Thus each
-            memory allocation will return a unique addresses, regardless of the
-            thread making the allocation request.</li>
-        </ul>
-
-        <ul>
-            <li>Automatic storage duration (stack) objects [3.7.2] accessed via
-            pointer or reference from another thread.</li>
-        </ul>
-
-        <ul>
-            <li>Resources provided by the operating system. For example,
-            files.</li>
-        </ul>
-
-        <ul>
-            <li>The program itself. In other words, each thread is executing
-            some function of the same program, not a totally different
-            program.</li>
-        </ul>
-
-        <p>Each thread has its own:</p>
-
-        <ul>
-            <li>Registers and current execution sequence (program counter)
-            [1.9/5].</li>
-        </ul>
-
-        <ul>
-            <li>Automatic storage duration (stack) objects [3.7.2].</li>

-        <h3><a name="Thread-safe">Thread-safe</a></h3>
-
-        <p>A program is thread-safe if it has no <a href="#Race condition">race
-        conditions</a>, does not <a href="#Deadlock">deadlock</a>, and has no
-        <a href="#Priority failure">priority failures</a>.</p>
-
-        <p>Note that thread-safety does not necessarily imply efficiency, and
-        than while some thread-safety violations can be determined statically
-        at compile time, many thread-safety errors can only only be detected at
-        runtime.</p>

+[section:emulations Emulations]
+[section:delete `=delete` emulation]
+
+C++11 allows to delete some implicitly generated functions as constructors and assignment using '= delete' as in
+
+  public:
+    thread(thread const&) = delete;
+
+On compilers not supporting this feature, Boost.Thread relays on a partial simulation, it declares the function as private without definition.
+
+  private:
+    thread(thread &);
+
+The emulation is partial as the private function can be used for overload resolution for some compilers and prefer it to other overloads that need a conversion. See below the consequences on the move semantic emulation.
+
+[endsect]
+
+[section:move Move semantics]
+
+In order to implement Movable classes, move parameters and return types Boost.Thread uses the rvalue reference when the compiler support it.
+On compilers not supporting it Boost.Thread uses either the emulation provided by Boost.Move or the emulation provided by the previous versions of Boost.Thread depending whether `BOOST_THREAD_USES_MOVE` is defined or not. This macros is unset by default when `BOOST_THREAD_VERSION` is 2. Since `BOOST_THREAD_VERSION` 3, `BOOST_THREAD_USES_MOVE` is defined.
+
+[section:deprecated Deprecated Version 2 interface]
+
+Previous to version 1.50, Boost.Thread make use of its own move semantic emulation which had more limitations than the provided by Boost.Move. In addition, it is of interest of the whole Boost community that Boost.Thread uses Boost.Move so that boost::thread can be stored on Movable aware containers.
+
+To preserve backward compatibility at least during some releases, Boost.Thread allows the user to use the deprecated move semantic emulation defining BOOST_THREAD_DONT_USE_MOVE.
+
+Many aspects of move semantics can be emulated for compilers not supporting rvalue references and Boost.Thread legacy offers tools for that purpose. 
+
+[section:Helper Helpers class and function]
+
+Next follows the interface of the legacy move semantic helper class and function. 
+
+  namespace boost
+  {
+    namespace detail
+    {
+        template<typename T>
+        struct thread_move_t
+        {
+          explicit thread_move_t(T& t_);
+          T& operator*() const;
+          T* operator->() const;
+        private:
+          void operator=(thread_move_t&);
+        };
+    }
+    template<typename T>
+    boost::detail::thread_move_t<T> move(boost::detail::thread_move_t<T> t);
+  }
+[endsect]
+
+[section:movable Movable emulation]
+
+We can write a MovableOny class as follows. You just need to follow these simple steps:
+
+* Add a conversion to the `detail::thread_move_t<classname>`
+* Make the copy constructor private.
+* Write a constructor taking the parameter as `detail::thread_move_t<classname>`
+* Write an assignment taking the parameter as `detail::thread_move_t<classname>`
+
+For example the thread class defines the following:
+
+    class thread 
+    {
+      // ...
+    private:
+        thread(thread&);
+        thread& operator=(thread&);
+    public:
+        detail::thread_move_t<thread> move()
+        {
+            detail::thread_move_t<thread> x(*this);
+            return x;
+        }    
+        operator detail::thread_move_t<thread>()
+        {
+            return move();
+        }
+        thread(detail::thread_move_t<thread> x)
+        {
+            thread_info=x->thread_info;
+            x->thread_info.reset();
+        }
+        thread& operator=(detail::thread_move_t<thread> x)
+        {
+            thread new_thread(x);
+            swap(new_thread);
+            return *this;
+        }
+      // ...
+
+    };
+
+[endsect]
+
+[endsect]
+
+[section:portable Portable interface]
+
+In order to make the library code portable Boost.Thread uses some macros that will use either the ones provided by Boost.Move or the deprecated move semantics provided by previous versions of Boost.Thread.
+
+See the Boost.Move documentation for a complete description on how to declare new Movable classes and its limitations.
+
+* `BOOST_THREAD_RV_REF(TYPE)` is the equivalent of `BOOST_RV_REF(TYPE)`
+* `BOOST_THREAD_RV_REF_BEG` is the equivalent of `BOOST_RV_REF_BEG(TYPE)`
+* `BOOST_THREAD_RV_REF_END` is the equivalent of `BOOST_RV_REF_END(TYPE)`
+* `BOOST_THREAD_FWD_REF(TYPE)` is the equivalent of `BOOST_FWD_REF(TYPE)
+
+In addition the following macros are needed to make the code portable:
+
+* `BOOST_THREAD_RV(V)` macro to access the rvalue from a BOOST_THREAD_RV_REF(TYPE), 
+* `BOOST_THREAD_MAKE_RV_REF(RVALUE)` makes a rvalue.
+* `BOOST_THREAD_DCL_MOVABLE(CLASS)` to avoid conflicts with Boost.Move
+* `BOOST_THREAD_DCL_MOVABLE_BEG(T1)` and `BOOST_THREAD_DCL_MOVABLE_END` are variant of `BOOST_THREAD_DCL_MOVABLE` when the parameter is a template instantiation.
+
+Other macros are provided and must be included on the public section:
+
+* `BOOST_THREAD_NO_COPYABLE` declares a class no-copyable either deleting the copy constructors and copy assignment or moving them to the private section. 
+* `BOOST_THREAD_MOVABLE(CLASS)` declares all the implicit conversions to an rvalue-reference. 
+* `BOOST_THREAD_MOVABLE_ONLY(CLASS)` is the equivalent of `BOOST_MOVABLE_BUT_NOT_COPYABLE(CLASS)`
+* `BOOST_THREAD_COPYABLE_AND_MOVABLE(CLASS)` is the equivalent of `BOOST_COPYABLE_AND_MOVABLE(CLASS)`
+
+
+[section:NO_COPYABLE `BOOST_THREAD_NO_COPYABLE(CLASS)`]
+
+This macro marks a class as no copyable, disabling copy construction and assignment. 
+
+[endsect] 
+
+[section:MOVABLE `BOOST_THREAD_MOVABLE(CLASS)`]
+
+This macro marks a class as movable, declaring all the implicit conversions to an rvalue-reference. 
+
+[endsect] 
+
+[section:MOVABLE_ONLY `BOOST_THREAD_MOVABLE_ONLY(CLASS)`]
+
+This macro marks a type as movable but not copyable, disabling copy construction and assignment. The user will need to write a move constructor/assignment to fully write a movable but not copyable class. 
+
+[endsect] 
+
+[section:COPYABLE_AND_MOVABLE `BOOST_THREAD_COPYABLE_AND_MOVABLE(CLASS)`]
+
+This macro marks a type as copyable and movable. The user will need to write a move constructor/assignment and a copy assignment to fully write a copyable and movable class. 
+
+[endsect] 
+
+[section:RV_REF `BOOST_THREAD_RV_REF(TYPE)`, `BOOST_THREAD_RV_REF_BEG` and `BOOST_THREAD_RV_REF_END`]
+
+This macro is used to achieve portable syntax in move constructors and assignments for classes marked as `BOOST_THREAD_COPYABLE_AND_MOVABLE` or `BOOST_THREAD_MOVABLE_ONLY`. 
+
+`BOOST_THREAD_RV_REF_BEG` and `BOOST_THREAD_RV_REF_END` are used when the parameter end with a `>` to avoid the compiler error.       
+
+[endsect] 
+
+[section:RV `BOOST_THREAD_RV(V)`]
+
+While Boost.Move emulation allows to access an rvalue reference `BOOST_THREAD_RV_REF(TYPE)` using the dot operator, the legacy defines the `operator->`. We need then a macro `BOOST_THREAD_RV` that mask this difference. E.g.
+
+        thread(BOOST_THREAD_RV_REF(thread) x)
+        {
+            thread_info=BOOST_THREAD_RV(x).thread_info;
+            BOOST_THREAD_RV(x).thread_info.reset();
+        }
+
+The use of this macros has reduced considerably the size of the Boost.Thread move related code.
+
+[endsect] 
+
+[section:MAKE_RV_REF `BOOST_THREAD_MAKE_RV_REF(RVALUE)`]
+
+While Boost.Move is the best C++03 move emulation there are some limitations that impact the way the library can be used. 
+For example, with the following declarations 
+
+  class thread {
+    // ...
+  private:
+    thread(thread &);
+  public:
+    thread(rv<thread>&);
+    // ...
+  };
+
+This could not work on some compilers even if thread is convertible to `rv<thread>` because the compiler prefers the private copy constructor.
+
+  thread mkth() 
+  {
+    return thread(f);
+  }
+
+On these compilers we need to use instead an explicit conversion. The library provides a move member function that allows to workaround the issue.  
+
+  thread mkth() 
+  {
+    return thread(f).move();
+  }
+
+Note that `::boost::move` can not be used in this case as thread is not implicitly convertible to `thread&`.
+
+  thread mkth() 
+  {
+    return ::boost::move(thread(f));
+  }
+
+To make the code portable Boost.Thread the user needs to use a macro `BOOST_THREAD_MAKE_RV_REF` that can be used as in 
+
+  thread mkth() 
+  {
+    return BOOST_THREAD_MAKE_RV_REF(thread(f));
+  }
+
+Note that this limitation is shared also by the legacy Boost.Thread move emulation.
+ 
+[endsect] 
+
+[section:DCL_MOVABLE `BOOST_THREAD_DCL_MOVABLE`, `BOOST_THREAD_DCL_MOVABLE_BEG(T1)` and `BOOST_THREAD_DCL_MOVABLE_END`]
+
+As Boost.Move defines also the `boost::move` function we need to specialize the `has_move_emulation_enabled_aux` metafunction.
+
+    template <>
+    struct has_move_emulation_enabled_aux<thread>
+      : BOOST_MOVE_BOOST_NS::integral_constant<bool, true>
+    {};
+
+so that the following Boost.Move overload is disabled
+
+   template <class T>
+   inline typename BOOST_MOVE_BOOST_NS::disable_if<has_move_emulation_enabled_aux<T>, T&>::type move(T& x);
+
+The macros `BOOST_THREAD_DCL_MOVABLE(CLASS)`, `BOOST_THREAD_DCL_MOVABLE_BEG(T1)` and `BOOST_THREAD_DCL_MOVABLE_END` are used for this purpose. E.g.
+
+    BOOST_THREAD_DCL_MOVABLE(thread)
+
+and
+
+    BOOST_THREAD_DCL_MOVABLE_BEG(T) promise<T> BOOST_THREAD_DCL_MOVABLE_END
+
+
+[endsect] 
+[endsect] 
+
+
+[endsect]
+
+[section:bool_explicit_conversion Bool explicit conversion]
+
+Locks provide an explicit bool conversion operator when the compiler provides them.
+
+  explicit operator bool() const;
+
+The library provides un implicit conversion to an undefined type that can be used as a conditional expression. 
+
+    #if defined(BOOST_NO_EXPLICIT_CONVERSION_OPERATORS)
+        operator ``['unspecified-bool-type]``() const;
+        bool operator!() const;
+    #else
+        explicit operator bool() const;
+    #endif
+
+The user should use the lock.owns_lock() when a explicit conversion is required. 
+
+[section:bool_conversion `operator `['unspecified-bool-type]`() const`]
+
+[variablelist
+
+[[Returns:] [If __owns_lock_ref__ would return `true`, a value that evaluates to
+`true` in boolean contexts, otherwise a value that evaluates to `false` in

+]
+
+[endsect]
+
+ 
+[endsect]
+
+[section:scoped_enums Scoped Enums]
+
+Some of the enumerations defined in the standard library are scoped enums. 
+
+On compilers that don't support them, the library uses a class to wrap the underlying type. Instead of 
+
+  enum class future_errc
+  {
+      broken_promise,
+      future_already_retrieved,
+      promise_already_satisfied,
+      no_state
+  };
+
+the library declare these types as
+
+  BOOST_SCOPED_ENUM_DECLARE_BEGIN(future_errc)
+  {
+      broken_promise,
+      future_already_retrieved,
+      promise_already_satisfied,
+      no_state
+  }
+  BOOST_SCOPED_ENUM_DECLARE_END(future_errc)
+
+These macros allows to use 'future_errc' in almost all the cases as an scoped enum.
+
+There are however some limitations:
+
+* The type is not a C++ enum, so 'is_enum<future_errc>' will be false_type.
+* The emulated scoped enum can not be used in switch nor in template arguments. For these cases the user needs to use some macros.
+
+Instead of
+
+        switch (ev)
+        {
+        case future_errc::broken_promise:
+	// ...
+
+use
+
+        switch (boost::native_value(ev))
+        {
+        case future_errc::broken_promise:
+
+And instead of
+
+    #ifdef BOOST_NO_SCOPED_ENUMS
+    template <>
+    struct BOOST_SYMBOL_VISIBLE is_error_code_enum<future_errc> : public true_type { };
+    #endif

+[section  External Locking -- `strict_lock` and `externally_locked` classes]
+
+
+[note This tutorial is an adaptation of the paper of Andrei Alexandrescu "Multithreading and the C++ Type System"
+to the Boost library.]
+
+[/
+[section  Internal locking]
+
+Consider, for example, modeling a bank account class that supports simultaneous deposits and withdrawals from multiple locations (arguably the "Hello, World" of multi-threaded programming). In the code below, guard's constructor locks the passed-in object this, and guard's destructor unlocks this.
+
+  class BankAccount {
+      boost::mutex mtx_; // explicit mutex declaration 
+      int balance_;
+  public:
+      void Deposit(int amount) {
+          boost::lock_guard<boost::mutex> guard(mtx_);
+          balance_ += amount;
+      }
+      void Withdraw(int amount) {
+          boost::lock_guard<boost::mutex> guard(mtx_);
+          balance_ -= amount;
+      }
+      int GetBalance() {
+          boost::lock_guard<boost::mutex> guard(mtx_);
+          return balance_;
+      }
+  };
+
+The object-level locking idiom doesn't cover the entire richness of a threading model. For example, the model above is quite deadlock-prone when you try to coordinate multi-object transactions. Nonetheless, object-level locking is useful in many cases, and in combination with other mechanisms can provide a satisfactory solution to many threaded access problems in object-oriented programs.
+
+[endsect]
+
+[section  Internal and external locking]
+
+The BankAccount class above uses internal locking. Basically, a class that uses internal locking guarantees that any concurrent calls to its public member functions don't corrupt an instance of that class. This is typically ensured by having each public member function acquire a lock on the object upon entry. This way, for any given object of that class, there can be only one member function call active at any moment, so the operations are nicely serialized.
+
+This approach is reasonably easy to implement and has an attractive simplicity. Unfortunately, "simple" might sometimes morph into "simplistic."
+
+Internal locking is insufficient for many real-world synchronization tasks. Imagine that you want to implement an ATM withdrawal transaction with the BankAccount class. The requirements are simple. The ATM transaction consists of two withdrawals-one for the actual money and one for the $2 commission. The two withdrawals must appear in strict sequence; that is, no other transaction can exist between them.
+
+The obvious implementation is erratic:
+
+  void ATMWithdrawal(BankAccount& acct, int sum) {
+      acct.Withdraw(sum);
+      // preemption possible
+      acct.Withdraw(2);
+  }
+
+The problem is that between the two calls above, another thread can perform another operation on the account, thus breaking the second design requirement.
+
+In an attempt to solve this problem, let's lock the account from the outside during the two operations:
+
+  void ATMWithdrawal(BankAccount& acct, int sum) {
+      boost::lock_guard<boost::mutex> guard(acct.mtx_); // mtx_ field is private
+      acct.Withdraw(sum);
+      acct.Withdraw(2);
+  }
+
+
+Notice that the code above doesn't compiles, the `mtx_` field is private.
+We have two possibilities:
+
+* make `mtx_` public which seams odd
+* make the `BankAccount` lockable by adding the lock/unlock functions
+
+We can add these functions explicitly
+
+  class BankAccount {
+      boost::mutex mtx_;
+      int balance_;
+  public:
+      void Deposit(int amount) {
+          boost::lock_guard<boost::mutex> guard(mtx_);
+          balance_ += amount;
+      }
+      void Withdraw(int amount) {
+          boost::lock_guard<boost::mutex> guard(mtx_);
+          balance_ -= amount;
+      }
+      void lock() {
+          mtx_.lock();
+      }
+      void unlock() {
+          mtx_.unlock();
+      }
+  };
+
+or inheriting from a class which add these lockable functions.
+
+The `basic_lockable_adapter` class helps to define the `BankAccount` class as
+
+  class BankAccount
+  : public basic_lockable_adapter<thread_mutex>
+  {
+      int balance_;
+  public:
+      void Deposit(int amount) {
+          boost::lock_guard<BankAccount> guard(*this);
+  //        boost::lock_guard<boost::mutex> guard(*this->mutex());
+          balance_ += amount;
+      }
+      void Withdraw(int amount) {
+          boost::lock_guard<BankAccount> guard(*this);
+  //        boost::lock_guard<boost::mutex> guard(*this->mutex());
+          balance_ -= amount;
+      }
+      int GetBalance() {
+          boost::lock_guard<BankAccount> guard(*this);
+  //        boost::lock_guard<boost::mutex> guard(*this->mutex());
+          return balance_;
+      }
+  };
+
+
+
+and the code that does not compiles becomes
+
+  void ATMWithdrawal(BankAccount& acct, int sum) {
+  //    boost::lock_guard<boost::mutex> guard(*acct.mutex());
+      boost::lock_guard<BankAccount> guard(acct);
+      acct.Withdraw(sum);
+      acct.Withdraw(2);
+  }
+
+Notice that now acct is being locked by Withdraw after it has already been locked by guard. When running such code, one of two things happens.
+
+* Your mutex implementation might support the so-called recursive mutex semantics. This means that the same thread can lock the same mutex several times successfully. In this case, the implementation works but has a performance overhead due to unnecessary locking. (The locking/unlocking sequence in  the two Withdraw calls is not needed but performed anyway-and that costs time.)
+* Your mutex implementation might not support recursive locking, which means that as soon as you try     to acquire it the second time, it blocks-so the ATMWithdrawal function enters the dreaded deadlock.
+
+As `boost::mutex` is not recursive, we need to use its recursive version `boost::recursive_mutex`.
+
+  class BankAccount
+  : public basic_lockable_adapter<recursive_mutex>
+  {
+  
+      // ...
+  };
+
+The caller-ensured locking approach is more flexible and the most efficient, but very dangerous. In an implementation using caller-ensured locking, BankAccount still holds a mutex, but its member functions don't manipulate it at all. Deposit and Withdraw are not thread-safe anymore. Instead, the client code is responsible for locking BankAccount properly.
+
+    class BankAccount
+        : public basic_lockable_adapter<boost:mutex> {
+        int balance_;
+    public:
+        void Deposit(int amount) {
+            balance_ += amount;
+        }
+        void Withdraw(int amount) {
+            balance_ -= amount;
+        }
+    };
+
+Obviously, the caller-ensured locking approach has a safety problem. BankAccount's implementation code is finite, and easy to reach and maintain, but there's an unbounded amount of client code that manipulates BankAccount objects. In designing applications, it's important to differentiate between requirements imposed on bounded code and unbounded code. If your class makes undue requirements on unbounded code, that's usually a sign that encapsulation is out the window.
+
+To conclude, if in designing a multi-threaded class you settle on internal locking, you expose yourself to inefficiency or deadlocks. On the other hand, if you rely on caller-provided locking, you make your class error-prone and difficult to use. Finally, external locking completely avoids the issue by leaving it all to the client code.
+[endsect]
+]
+[section  Locks as Permits]
+
+So what to do? Ideally, the BankAccount class should do the following:
+
+* Support both locking models (internal and external).
+* Be efficient; that is, use no unnecessary locking.
+* Be safe; that is, BankAccount objects cannot be manipulated without appropriate locking.
+
+Let's make a worthwhile observation: Whenever you lock a BankAccount, you do so by using a `lock_guard<BankAccount>` object. Turning this statement around, wherever there's a `lock_guard<BankAccount>`, there's also a locked `BankAccount` somewhere. Thus, you can think of-and use-a `lock_guard<BankAccount>` object as a permit. Owning a `lock_guard<BankAccount>` gives you rights to do certain things. The `lock_guard<BankAccount>` object should not be copied or aliased (it's not a transmissible permit).
+
+# As long as a permit is still alive, the `BankAccount` object stays locked.
+# When the `lock_guard<BankAccount>` is destroyed, the `BankAccount`'s mutex is released.
+
+The net effect is that at any point in your code, having access to a `lock_guard<BankAccount>` object guarantees that a `BankAccount` is locked. (You don't know exactly which `BankAccount` is locked, however-an issue that we'll address soon.)
+
+For now, let's make a couple of enhancements to the `lock_guard` class template defined in Boost.Thread. 
+We'll call the enhanced version `strict_lock`. Essentially, a `strict_lock`'s role is only to live on the stack as an automatic variable. 
+`strict_lock` must adhere to a non-copy and non-alias policy. 
+`strict_lock` disables copying by making the copy constructor and the assignment operator private. 
+While we're at it, let's disable operator new and operator delete; 
+`strict_lock` are not intended to be allocated on the heap. 
+`strict_lock` avoids aliasing by using a slightly less orthodox and less well-known technique: disable address taking.
+
+
+    template <typename Lockable>
+    class strict_lock  {
+    public:
+        typedef Lockable lockable_type;
+        
+        
+        explicit strict_lock(lockable_type& obj) : obj_(obj) {
+            obj.lock(); // locks on construction
+        }
+        strict_lock() = delete;
+        strict_lock(strict_lock const&) = delete;
+        strict_lock& operator=(strict_lock const&) = delete;
+        
+        ~strict_lock() { obj_.unlock(); } //  unlocks on destruction 
+
+        bool owns_lock(mutex_type const* l) const noexcept // strict lockers specific function 
+        { 
+          return l == &obj_;
+        }
+    private:
+        lockable_type& obj_;
+    };
+
+Silence can be sometimes louder than words-what's forbidden to do with a `strict_lock` is as important as what you can do. Let's see what you can and what you cannot do with a `strict_lock` instantiation:
+
+* You can create a `strict_lock<T>` only starting from a valid T object. Notice that there is no other way you can create a `strict_lock<T>`.
+
+    BankAccount myAccount("John Doe", "123-45-6789");
+    strict_locerk<BankAccount> myLock(myAccount); // ok
+
+* You cannot copy `strict_lock`s to one another. In particular, you cannot pass `strict_lock`s by value to functions or have them returned by functions:
+
+      extern strict_lock<BankAccount> Foo(); // compile-time error
+      extern void Bar(strict_lock<BankAccount>); // compile-time error
+
+* However, you still can pass `strict_lock`s by reference to and from functions:
+
+    // ok, Foo returns a reference to strict_lock<BankAccount>
+    extern strict_lock<BankAccount>& Foo();
+    // ok, Bar takes a reference to strict_lock<BankAccount>
+    extern void Bar(strict_lock<BankAccount>&);
+
+* You cannot allocate a `strict_lock` on the heap. However, you still can put `strict_lock`s on the heap if they're members of a class.
+
+    strict_lock<BankAccount>* pL =
+        new strict_lock<BankAccount>(myAcount); //error!
+        // operator new is not accessible
+    class Wrapper {
+        strict_lock memberLock_;
+        ...
+    };
+    Wrapper* pW = new Wrapper; // ok
+
+(Making `strict_lock` a member variable of a class is not recommended. Fortunately, disabling copying and default construction makes `strict_lock` quite an unfriendly member variable.)
+
+* You cannot take the address of a `strict_lock` object. This interesting feature, implemented by disabling unary operator&, makes it very unlikely to alias a `strict_lock` object. Aliasing is still possible by taking references to a `strict_lock`:
+
+    strict_lock<BankAccount> myLock(myAccount); // ok
+    strict_lock<BankAccount>* pAlias = &myLock; // error!
+        // strict_lock<BankAccount>::operator& is not accessible
+    strict_lock<BankAccount>& rAlias = myLock; // ok
+
+Fortunately, references don't engender as bad aliasing as pointers because they're much less versatile (references cannot be copied or reseated).
+
+* You can even make `strict_lock` final; that is, impossible to derive from. This task is left in the form of an exercise to the reader.
+
+All these rules were put in place with one purpose-enforcing that owning a `strict_lock<T>` is a reasonably strong guarantee that
+
+# you locked a T object, and
+# that object will be unlocked at a later point.
+
+Now that we have such a strict `strict_lock`, how do we harness its power in defining a safe, flexible interface for BankAccount? The idea is as follows:
+
+* Each of BankAccount's interface functions (in our case, Deposit and Withdraw) comes in two overloaded variants.
+* One version keeps the same signature as before, and the other takes an additional argument of type `strict_lock<BankAccount>`. The first version is internally locked; the second one requires external locking. External locking is enforced at compile time by requiring client code to create a `strict_lock<BankAccount>` object.
+* BankAccount avoids code bloating by having the internal locked functions forward to the external locked functions, which do the actual job.
+
+A little code is worth 1,000 words, a (hacked into) saying goes, so here's the new BankAccount class:
+
+    class BankAccount
+    : public basic_lockable_adapter<boost:recursive_mutex>
+    {
+        int balance_;
+    public:
+        void Deposit(int amount, strict_lock<BankAccount>&) {
+            // Externally locked
+            balance_ += amount;
+        }
+        void Deposit(int amount) {
+            strict_lock<boost:mutex> guard(*this); // Internally locked
+            Deposit(amount, guard);
+        }
+        void Withdraw(int amount, strict_lock<BankAccount>&) {
+            // Externally locked
+            balance_ -= amount;
+        }
+        void Withdraw(int amount) {
+            strict_lock<boost:mutex> guard(*this); // Internally locked
+            Withdraw(amount, guard);
+        }
+    };
+
+Now, if you want the benefit of internal locking, you simply call Deposit(int) and Withdraw(int). If you want to use external locking, you lock the object by constructing a `strict_lock<BankAccount>` and then you call `Deposit(int, strict_lock<BankAccount>&)` and `Withdraw(int, strict_lock<BankAccount>&)`. For example, here's the `ATMWithdrawal` function implemented correctly:
+
+    void ATMWithdrawal(BankAccount& acct, int sum) {
+        strict_lock<BankAccount> guard(acct);
+        acct.Withdraw(sum, guard);
+        acct.Withdraw(2, guard);
+    }
+
+This function has the best of both worlds-it's reasonably safe and efficient at the same time.
+
+It's worth noting that `strict_lock` being a template gives extra safety compared to a straight polymorphic approach. In such a design, BankAccount would derive from a Lockable interface. `strict_lock` would manipulate Lockable references so there's no need for templates. This approach is sound; however, it provides fewer compile-time guarantees. Having a `strict_lock` object would only tell that some object derived from Lockable is currently locked. In the templated approach, having a `strict_lock<BankAccount>` gives a stronger guarantee-it's a `BankAccount` that stays locked.
+
+There's a weasel word in there-I mentioned that ATMWithdrawal is reasonably safe. It's not really safe because there's no enforcement that the `strict_lock<BankAccount>` object locks the appropriate BankAccount object. The type system only ensures that some BankAccount object is locked. For example, consider the following phony implementation of ATMWithdrawal:
+
+    void ATMWithdrawal(BankAccount& acct, int sum) {
+        BankAccount fakeAcct("John Doe", "123-45-6789");
+        strict_lock<BankAccount> guard(fakeAcct);
+        acct.Withdraw(sum, guard);
+        acct.Withdraw(2, guard);
+    }
+
+This code compiles warning-free but obviously doesn't do the right thing-it locks one account and uses another.
+
+It's important to understand what can be enforced within the realm of the C++ type system and what needs to be enforced at runtime. The mechanism we've put in place so far ensures that some BankAccount object is locked during the call to `BankAccount::Withdraw(int, strict_lock<BankAccount>&)`. We must enforce at runtime exactly what object is locked.
+
+If our scheme still needs runtime checks, how is it useful? An unwary or malicious programmer can easily lock the wrong object and manipulate any BankAccount without actually locking it.
+
+First, let's get the malice issue out of the way. C is a language that requires a lot of attention and discipline from the programmer. C++ made some progress by asking a little less of those, while still fundamentally trusting the programmer. These languages are not concerned with malice (as Java is, for example). After all, you can break any C/C++ design simply by using casts "appropriately" (if appropriately is an, er, appropriate word in this context).
+
+The scheme is useful because the likelihood of a programmer forgetting about any locking whatsoever is much greater than the likelihood of a programmer who does remember about locking, but locks the wrong object.
+
+Using `strict_lock` permits compile-time checking of the most common source of errors, and runtime checking of the less frequent problem.
+
+Let's see how to enforce that the appropriate BankAccount object is locked. First, we need to add a member function to the `strict_lock` class template. 
+The `bool strict_lock<T>::owns_lock(Loclable*)` function returns a reference to the locked object.
+
+    template <class Lockable> class strict_lock {
+        ... as before ...
+    public:
+        bool owns_lock(Lockable* mtx) const { return mtx==&obj_; }
+    };
+
+Second, BankAccount needs to use this function compare the locked object against this:
+
+    class BankAccount {
+    : public basic_lockable_adapter<boost::recursive_mutex>
+        int balance_;
+    public:
+        void Deposit(int amount, strict_lock<BankAccount>& guard) {
+            // Externally locked
+            if (!guard.owns_lock(*this))
+                throw "Locking Error: Wrong Object Locked";
+            balance_ += amount;
+        }
+    // ...
+    };
+
+The overhead incurred by the test above is much lower than locking a recursive mutex for the second time.
+
+[endsect]
+
+[section  Improving External Locking]
+
+Now let's assume that BankAccount doesn't use its own locking at all, and has only a thread-neutral implementation:
+
+    class BankAccount {
+        int balance_;
+    public:
+        void Deposit(int amount) {
+            balance_ += amount;
+        }
+        void Withdraw(int amount) {
+            balance_ -= amount;
+        }
+    };
+
+Now you can use BankAccount in single-threaded and multi-threaded applications alike, but you need to provide your own synchronization in the latter case.
+
+Say we have an AccountManager class that holds and manipulates a BankAccount object:
+
+    class AccountManager
+    : public basic_lockable_adapter<boost::mutex>
+    {
+        BankAccount checkingAcct_;
+        BankAccount savingsAcct_;
+        ...
+    };
+
+Let's also assume that, by design, AccountManager must stay locked while accessing its BankAccount members. The question is, how can we express this design constraint using the C++ type system? How can we state "You have access to this BankAccount object only after locking its parent AccountManager object"?
+
+The solution is to use a little bridge template `externally_locked` that controls access to a BankAccount.
+
+  template <typename  T, typename Lockable>
+  class externally_locked {
+      BOOST_CONCEPT_ASSERT((LockableConcept<Lockable>));
+  
+  public:
+      externally_locked(T& obj, Lockable& lockable)
+          : obj_(obj)
+          , lockable_(lockable)
+      {}
+  
+      externally_locked(Lockable& lockable)
+          : obj_()
+          , lockable_(lockable)
+      {}
+  
+      T& get(strict_lock<Lockable>& lock) {
+  
+  #ifndef BOOST_THREAD_EXTERNALLY_LOCKED_DONT_CHECK_SAME  // define BOOST_THREAD_EXTERNALLY_LOCKED_DONT_CHECK_SAME if you don't want to check locker check the same lockable
+          if (!lock.is_locking(&lockable_)) throw lock_error(); run time check throw if not locks the same
+  #endif
+          return obj_;
+      }
+      void set(const T& obj, Lockable& lockable) {
+          obj_ = obj;
+          lockable_=lockable;
+      }
+  private:
+      T obj_;
+      Lockable& lockable_;
+  };
+
+`externally_locked` cloaks an object of type T, and actually provides full access to that object through the get and set member functions, provided you pass a reference to a `strict_lock<Owner>` object.
+
+Instead of making `checkingAcct_` and `savingsAcct_` of type `BankAccount`, `AccountManager` holds objects of type `externally_locked<BankAccount, AccountManager>`:
+
+  class AccountManager
+      : public basic_lockable_adapter<thread_mutex>
+  {
+  public:
+      typedef basic_lockable_adapter<thread_mutex> lockable_base_type;
+      AccountManager()
+          : checkingAcct_(*this)
+          , savingsAcct_(*this)
+      {}
+      inline void Checking2Savings(int amount);
+      inline void AMoreComplicatedChecking2Savings(int amount);
+  private:
+      
+      externally_locked<BankAccount, AccountManager> checkingAcct_;
+      externally_locked<BankAccount, AccountManager> savingsAcct_;
+  };
+
+The pattern is the same as before - to access the BankAccount object cloaked by `checkingAcct_`, you need to call `get`. To call `get`, you need to pass it a `strict_lock<AccountManager>`. The one thing you have to take care of is to not hold pointers or references you obtained by calling `get`. If you do that, make sure that you don't use them after the strict_lock has been destroyed. That is, if you alias the cloaked objects, you're back from "the compiler takes care of that" mode to "you must pay attention" mode.
+
+Typically, you use `externally_locked` as shown below. Suppose you want to execute an atomic transfer from your checking account to your savings account:
+
+  void AccountManager::Checking2Savings(int amount) {
+      strict_lock<AccountManager> guard(*this);
+      checkingAcct_.get(guard).Withdraw(amount);
+      savingsAcct_.get(guard).Deposit(amount);
+  }
+
+We achieved two important goals. First, the declaration of `checkingAcct_` and `savingsAcct_` makes it clear to the code reader that that variable is protected by a lock on an AccountManager. Second, the design makes it impossible to manipulate the two accounts without actually locking a BankAccount. `externally_locked` is what could be called active documentation.
+
+[endsect]
+
+[section  Allowing other strict locks]
+
+Now imagine that the AccountManager function needs to take a `unique_lock` in order to reduce the critical regions. And at some time it needs to access to the `checkingAcct_`. As `unique_lock` is not a strict lock the following code doesn't compiles:
+
+  void AccountManager::AMoreComplicatedChecking2Savings(int amount) {
+      unique_lock<AccountManager> guard(*this, defer_lock);
+      if (some_condition()) {
+          guard.lock();
+      }
+      checkingAcct_.get(guard).Withdraw(amount); // COMPILE ERROR
+      savingsAcct_.get(guard).Deposit(amount);  // COMPILE ERROR
+      do_something_else();
+  }
+
+We need a way to transfer the ownership from the `unique_lock` to a `strict_lock` the time we are working with `savingsAcct_` and then restore the ownership on `unique_lock`.
+
+  void AccountManager::AMoreComplicatedChecking2Savings(int amount) {
+      unique_lock<AccountManager> guard(*this, defer_lock);
+      if (some_condition()) {
+          guard1.lock();
+      }
+      {
+          strict_lock<AccountManager> guard(guard1);
+          checkingAcct_.get(guard).Withdraw(amount);
+          savingsAcct_.get(guard).Deposit(amount);
+      }
+      guard1.unlock();
+  }
+
+In order to make this code compilable we need to store either a Lockable or a `unique_lock<Lockable>` reference depending on the constructor. Store which kind of reference we have stored,and in the destructor call either to the Lockable `unlock` or restore the ownership.
+
+This seams too complicated to me. Another possibility is to define a nested strict lock class. The drawback is that instead of having only one strict lock we have two and we need either to duplicate every function taking a `strict\_lock` or make these function templates functions. The problem with template functions is that we don't profit anymore of the C++ type system. We must add some static metafunction that check that the Locker parameter is a strict lock. The problem is that we can not really check this or can we?. The `is_strict_lock` metafunction must be specialized by the strict lock developer. We need to belive it "sur parolle". The advantage is that now we can manage with more than two strict locks without changing our code. Ths is really nice.
+
+Now we need to state that both classes are `strict_lock`s.
+
+    template <typename Locker>
+    struct is_strict_lock : mpl::false_ {};
+
+    template <typename Lockable>
+    struct is_strict_lock<strict_lock<Lockable> > : mpl::true_ {}
+
+    template <typename Locker>
+    struct is_strict_lock<nested_strict_lock<Locker> > : mpl::true_ {}
+
+
+Well let me show how this `nested_strict_lock` class looks like and the impacts on the `externally_locked` class and the `AccountManager::AMoreComplicatedFunction` function.
+
+First `nested_strict_lock` class will store on a temporary lock the `Locker`, and transfer the lock ownership on the constructor. On destruction he will restore the ownership. Note also that the Locker needs to have already a reference to the mutex otherwise an exception is thrown and the use of the `lock_traits`.
+
+  template <typename Locker >
+  class nested_strict_lock
+      {
+        BOOST_CONCEPT_ASSERT((MovableLockerConcept<Locker>));
+  public:
+      typedef typename lockable_type<Locker>::type lockable_type;
+      typedef typename syntactic_lock_traits<lockable_type>::lock_error lock_error;
+  
+      nested_strict_lock(Locker& lock)
+          : lock_(lock)  // Store reference to locker
+          , tmp_lock_(lock.move()) // Move ownership to temporaty locker 
+      {
+          #ifndef BOOST_THREAD_STRCIT_LOCKER_DONT_CHECK_OWNERSHIP  // Define BOOST_THREAD_EXTERNALLY_LOCKED_DONT_CHECK_OWNERSHIP if you don't want to check locker ownership
+          if (tmp_lock_.mutex()==0) {
+              lock_=tmp_lock_.move(); // Rollback for coherency purposes 
+              throw lock_error();
+          }
+          #endif
+          if (!tmp_lock_) tmp_lock_.lock(); // ensures it is locked 
+      }
+      ~nested_strict_lock() {
+          lock_=tmp_lock_.move(); // Move ownership to nesting locker 
+      }
+      typedef bool (nested_strict_lock::*bool_type)() const;
+      operator bool_type() const { return &nested_strict_lock::owns_lock; }

-        <h2>1. Are lock objects <a href="definitions.html#Thread-safe">
-        thread-safe</a>?</h2>
-
-        <p><b>No!</b> Lock objects are not meant to be shared between threads.
-        They are meant to be short lived objects created on automatic storage
-        within a code block. Any other usage is just likely to lead to errors
-        and won&#39;t really be of actual benefit any way. Share <a href=
-        "mutex_concept.html">mutexes</a>, not locks. For more information see
-        the <a href="rationale.html#lock_objects">rationale</a> behind the
-        design for lock objects.</p>
-
-        <h2>2a. Why was Boost.Threads modeled after (specific library
-        name)?</h2>
-
-        <p>It wasn&#39;t. Boost.Threads was designed from scratch. Extensive
-        design discussions involved numerous people representing a wide range
-        of experience across many platforms. To ensure portability, the initial
-        implements were done in parallel using POSIX Threads and theWin32
-        threading API. But the Boost.Threads design is very much in the spirit
-        of C++, and thus doesn&#39;t model such C based APIs.</p>
-
-        <h2>2b. Why wasn&#39;t Boost.Threads modeled after (specific library
-        name)?</h2>
-
-        <p>Existing C++ libraries either seemed dangerous (often failing to
-        take advantage of prior art to reduce errors) or had excessive
-        dependencies on library components unrelated to threading. Existing C
-        libraries couldn&#39;t meet our C++ requirements, and were also missing
-        certain features. For instance, the WIN32 thread API lacks condition
-        variables, even though these are critical for the important Monitor
-        pattern <a href="bibliography.html#Schmidt-00">[Schmidt 00]</a>.</p>
-
-        <h2>3. Why do <a href="mutex_concept.html">Mutexes</a> have noncopyable
-        semantics?</h2>
-
-        <p>To ensure that <a href="definitions.html#Deadlock">deadlocks</a>
-        don&#39;t occur. The only logical form of copy would be to use some
-        sort of shallow copy semantics in which multiple mutex objects could
-        refer to the same mutex state. This means that if ObjA has a mutex
-        object as part of its state and ObjB is copy constructed from it, then
-        when ObjB::foo() locks the mutex it has effectively locked ObjA as
-        well. This behavior can result in deadlock. Other copy semantics result
-        in similar problems (if you think you can prove this to be wrong then
-        supply us with an alternative and we&#39;ll reconsider).</p>
-
-        <h2>4. How can you prevent <a href="definitions.html#Deadlock">
-        deadlock</a> from occurring when a thread must lock multiple
-        mutexes?</h2>
-
-        <p>Always lock them in the same order. One easy way of doing this is to
-        use each mutex&#39;s address to determine the order in which they are
-        locked. A future Boost.Threads concept may wrap this pattern up in a
-        reusable class.</p>
-
-        <h2>5. Don&#39;t noncopyable <a href="mutex_concept.html">mutex</a>
-        semantics mean that a class with a mutex member will be noncopyable as
-        well?</h2>
-
-        <p>No, but what it does mean is that the compiler can&#39;t generate a
-        copy constructor and assignment operator, so they will have to be coded
-        explicitly. This is a <b>good thing</b>, however, since the compiler
-        generated operations would not be <a href=
-        "definitions.html#Thread-safe">thread-safe</a>. The following is a
-        simple example of a class with copyable semantics and internal
-        synchronization through a mutex member.</p>
-<pre>
-class counter
-{
-public:
-   // Doesn't need synchronization since there can be no references to *this
-   // until after it's constructed!
-   explicit counter(int initial_value)
-      : m_value(initial_value)
-   {
-   }
-   
-   // We only need to syncronize other for the same reason we don't have to
-   // synchronize on construction!
-   counter(const counter&amp; other)
-   {
-      boost::mutex::scoped_lock scoped_lock(other.m_mutex);
-      m_value = other.m_value;
-   }
-   
-   // For assignment we need to synchronize both objects!
-   const counter&amp; operator=(const counter&amp; other)
-   {
-      if (this == &amp;other)
-         return *this;
-         
-      boost::mutex::scoped_lock lock1(&amp;m_mutex &lt; &amp;other.m_mutex ? m_mutex : other.m_mutex);
-      boost::mutex::scoped_lock lock2(&amp;m_mutex &gt; &amp;other.m_mutex ? m_mutex : other.m_mutex);
-      m_value = other.m_value;
-      
-      return *this;
-   }
-   
-   int value() const
-   {
-      boost::mutex::scoped_lock scoped_lock(m_mutex);

-   }
-   int increment()

-      boost::mutex::scoped_lock scoped_lock(m_mutex);
-      return ++m_value;
-   }

-        <h2>6. How can you lock a <a href="mutex_concept.html">mutex</a> member
-        in a const member function, in order to implement the Monitor
-        Pattern?</h2>
-
-        <p>The Monitor Pattern mutex <a href="bibliography.html#Schmidt-00">
-        [Schmidt 00]</a> should simply be declared as mutable. See the example
-        code above. The internal state of mutex types could have been made
-        mutable, with all lock calls made via const functions, but this does a
-        poor job of documenting the actual semantics. Declaring a mutex member
-        as mutable clearly documentations the intended semantics.</p>
-
-        <h2>7. Why supply <a href="condition.html">condition variables</a>
-        rather than <a href="rationale.html#Events">event variables</a>?</h2>
-
-        <p>Condition variables result in user code much less prone to <a href=
-        "definitions.html#Race condition">race conditions</a> than event
-        variables. See <a href="rationale.html#Events">Rationale</a> for
-        analysis. Also see <a href="bibliography.html#Hoare-74">[Hoare74]</a>
-        and <a href="bibliography.html#Schmidt-00">[Schmidt 00]</a>.</p>
-
-        <h2>8. Why isn&#39;t thread cancellation or termination provided?</h2>
-
-        <p>There&#39;s a valid need for thread termination, so at some point
-        Boost.Threads probably will include it, but only after we can find a
-        truly safe (and portable) mechanism for this concept.</p>
-
-        <h2>9. Is it safe for threads to share automatic storage duration
-        (stack) objects via pointers or references?</h2>
-
-        <p>Only if you can guarantee that the lifetime of the stack object will
-        not end while other threads might still access the object. Thus the
-        safest practice is to avoid sharing stack objects, particularly in
-        designs where threads are created and destroyed dynamically. Restrict
-        sharing of stack objects to simple designs with very clear and
-        unchanging function and thread lifetimes. (Suggested by Darryl
-        Green).</p>
-
-        <h2>10. Why has class semaphore disappeared?</h2>
-
-        <p>Semaphore was removed as too error prone. The same effect can be
-        achieved with greater safety by the combination of a mutex and a
-        condition variable.</p>

+
+[section:overview Overview]
+
+The futures library provides a means of handling synchronous future values, whether those values are generated by another thread, or
+on a single thread in response to external stimuli, or on-demand.
+
+This is done through the provision of four class templates: __unique_future__ and __shared_future__ which are used to retrieve the
+asynchronous results, and __promise__ and __packaged_task__ which are used to generate the asynchronous results.
+
+An instance of __unique_future__ holds the one and only reference to a result. Ownership can be transferred between instances using
+the move constructor or move-assignment operator, but at most one instance holds a reference to a given asynchronous result. When
+the result is ready, it is returned from __unique_future_get__ by rvalue-reference to allow the result to be moved or copied as
+appropriate for the type.
+
+On the other hand, many instances of __shared_future__ may reference the same result. Instances can be freely copied and assigned,
+and __shared_future_get__ returns a non `const` reference so that multiple calls to __shared_future_get__ are safe. You can move an
+instance of __unique_future__ into an instance of __shared_future__, thus transferring ownership of the associated asynchronous
+result, but not vice-versa.
+
+`boost::async` is a simple way of running asynchronous tasks. A call to `boost::async` returns a __unique_future__ that will contain the result of the task.
+
+
+You can wait for futures either individually or with one of the __wait_for_any__ and __wait_for_all__ functions.
+
+[endsect]
+
+[section:creating Creating asynchronous values]
+
+You can set the value in a future with either a __promise__ or a __packaged_task__. A __packaged_task__ is a callable object that
+wraps a function or callable object. When the packaged task is invoked, it invokes the contained function in turn, and populates a
+future with the return value. This is an answer to the perennial question: "how do I return a value from a thread?": package the
+function you wish to run as a __packaged_task__ and pass the packaged task to the thread constructor. The future retrieved from the
+packaged task can then be used to obtain the return value. If the function throws an exception, that is stored in the future in
+place of the return value.
+
+    int calculate_the_answer_to_life_the_universe_and_everything()
+    {
+        return 42;
+    }
+
+    boost::packaged_task<int> pt(calculate_the_answer_to_life_the_universe_and_everything);
+    boost::__unique_future__<int> fi=pt.get_future();
+
+    boost::thread task(boost::move(pt)); // launch task on a thread
+
+    fi.wait(); // wait for it to finish
+        
+    assert(fi.is_ready());
+    assert(fi.has_value());
+    assert(!fi.has_exception());
+    assert(fi.get_state()==boost::future_state::ready);
+    assert(fi.get()==42);
+
+
+A __promise__ is a bit more low level: it just provides explicit functions to store a value or an exception in the associated
+future. A promise can therefore be used where the value may come from more than one possible source, or where a single operation may
+produce multiple values.
+
+    boost::promise<int> pi;
+    boost::__unique_future__<int> fi;
+    fi=pi.get_future();
+
+    pi.set_value(42);
+    
+    assert(fi.is_ready());
+    assert(fi.has_value());
+    assert(!fi.has_exception());
+    assert(fi.get_state()==boost::future_state::ready);
+    assert(fi.get()==42);
+
+[endsect]
+
+[section:lazy_futures Wait Callbacks and Lazy Futures]
+
+Both __promise__ and __packaged_task__ support ['wait callbacks] that are invoked when a thread blocks in a call to `wait()` or
+`timed_wait()` on a future that is waiting for the result from the __promise__ or __packaged_task__, in the thread that is doing the
+waiting. These can be set using the `set_wait_callback()` member function on the __promise__ or __packaged_task__ in question.
+
+This allows ['lazy futures] where the result is not actually computed until it is needed by some thread. In the example below, the
+call to `f.get()` invokes the callback `invoke_lazy_task`, which runs the task to set the value. If you remove the call to
+`f.get()`, the task is not ever run.
+
+    int calculate_the_answer_to_life_the_universe_and_everything()
+    {
+        return 42;
+    }
+
+    void invoke_lazy_task(boost::packaged_task<int>& task)
+    {
+        try
+        {
+            task();
+        }
+        catch(boost::task_already_started&)
+        {}
+    }
+
+    int main()
+    {
+        boost::packaged_task<int> task(calculate_the_answer_to_life_the_universe_and_everything);
+        task.set_wait_callback(invoke_lazy_task);
+        boost::__unique_future__<int> f(task.get_future());
+
+        assert(f.get()==42);
+    }
+
+
+[endsect]
+
+[section:at_thread_exit Handling Detached Threads and Thread Specific Variables]
+
+Detached threads pose a problem for objects with thread storage duration. 
+If we use a mechanism other than `thread::__join` to wait for a __thread to complete its work - such as waiting for a future to be ready - 
+then the destructors of thread specific variables will still be running after the waiting thread has resumed. 
+This section explain how the standard mechanism can be used to make such synchronization safe by ensuring that the 
+objects with thread storage duration are destroyed prior to the future being made ready. e.g.
+
+  int find_the_answer(); // uses thread specific objects
+  void thread_func(boost::promise<int>&& p)
+  {
+      p.set_value_at_thread_exit(find_the_answer());
+  }
+  
+  int main()
+  {
+      boost::promise<int> p;
+      boost::thread t(thread_func,boost::move(p));
+      t.detach(); // we're going to wait on the future
+      std::cout<<p.get_future().get()<<std::endl;
+  }
+
+When the call to `get()` returns, we know that not only is the future value ready, but the thread specific variables 
+on the other thread have also been destroyed.
+
+Such mechanisms are provided for `boost::condition_variable`, `boost::promise` and `boost::packaged_task`. e.g.
+
+  void task_executor(boost::packaged_task<void(int)> task,int param)
+  {
+      task.make_ready_at_thread_exit(param); // execute stored task
+  } // destroy thread specific and wake threads waiting on futures from task
+
+Other threads can wait on a future obtained from the task without having to worry about races due to the execution of 
+destructors of the thread specific objects from the task's thread.
+
+  boost::condition_variable cv;
+  boost::mutex m;
+  complex_type the_data;
+  bool data_ready;
+  
+  void thread_func()
+  {
+      boost::unique_lock<std::mutex> lk(m);
+      the_data=find_the_answer();
+      data_ready=true;
+      boost::notify_all_at_thread_exit(cv,boost::move(lk));
+  } // destroy thread specific objects, notify cv, unlock mutex
+  
+  void waiting_thread()
+  {
+      boost::unique_lock<std::mutex> lk(m);
+      while(!data_ready)
+      {
+          cv.wait(lk);
+      }
+      process(the_data);
+  }
+
+The waiting thread is guaranteed that the thread specific objects used by `thread_func()` have been destroyed by the time 
+`process(the_data)` is called. If the lock on `m` is released and re-acquired after setting `data_ready` and before calling 
+`boost::notify_all_at_thread_exit()` then this does NOT hold, since the thread may return from the wait due to a 
+spurious wake-up.

+
+[section:async Executing asynchronously]
+
+`boost::async` is a simple way of running asynchronous tasks to make use of the available hardware concurrency. 
+A call to `boost::async` returns a `boost::future` that will contain the result of the task. Depending on 
+the launch policy, the task is either run asynchronously on its own thread or synchronously on whichever thread
+calls the `wait()` or `get()` member functions on that `future`.
+
+A launch policy of either boost::launch::async, which asks the runtime to create an asynchronous thread,
+or boost::launch::deferred, which indicates you simply want to defer the function call until a later time (lazy evaluation). 
+This argument is optional - if you omit it your function will use the default policy.
+
+For example, consider computing the sum of a very large array. The first task is to not compute asynchronously when 
+the overhead would be significant. The second task is to split the work into two pieces, one executed by the host 
+thread and one executed asynchronously.
+
+
+    int parallel_sum(int* data, int size)
+    {
+      int sum = 0;
+      if ( size < 1000 )
+        for ( int i = 0; i < size; ++i )
+          sum += data[i];
+      else {
+        auto handle = boost::async(parallel_sum, data+size/2, size-size/2);
+        sum += parallel_sum(data, size/2);
+        sum += handle.get();
+      }
+      return sum;
+    }
+
+
+
+[endsect]
+
+[section:shared Shared Futures]
+
+`shared_future` is designed to be shared between threads, 
+that is to allow multiple concurrent get operations.
+
+[heading Multiple get]
+
+The second `get()` call in the following example future  
+
+  void bad_second_use( type arg ) {
+      
+    auto ftr = async( [=]{ return work( arg ); } );
+      if ( cond1 ) 
+      {
+          use1( ftr.get() );
+      } else 
+      {
+          use2( ftr.get() );
+      }
+      use3( ftr.get() ); // second use is undefined
+  }
+    
+Using a `shared_mutex` solves the issue
+
+  void good_second_use( type arg ) {
+      
+     shared_future<type> ftr = async( [=]{ return work( arg ); } );
+      if ( cond1 ) 
+      {
+          use1( ftr.get() );
+      } else 
+      {
+          use2(  ftr.get() );
+      }
+      use3( ftr.get() ); // second use is defined
+  }
+
+[heading share()]
+  
+Namming the return type when declaring the `shared_future` is needed; auto is not available within template argument lists. 
+Here `share()` could be used to simplify the code
+
+  void better_second_use( type arg ) {
+      
+     auto ftr = async( [=]{ return work( arg ); } ).share();
+      if ( cond1 ) 
+      {
+          use1( ftr.get() );
+      } else 
+      {
+          use2(  ftr.get() );
+      }
+      use3( ftr.get() ); // second use is defined
+  }
+ 
+[heading Writting on get()]
+
+The user can either read or write the future avariable. 
+
+  void write_to_get( type arg ) {
+      
+     auto ftr = async( [=]{ return work( arg ); } ).share();
+      if ( cond1 ) 
+      {
+          use1( ftr.get() );
+      } else 
+      {
+        if ( cond2 ) 
+          use2(  ftr.get() );
+        else
+          ftr.get() = something(); // assign to non-const reference.  
+      }
+      use3( ftr.get() ); // second use is defined
+  }
+     
+This works because the `shared_future<>::get()` function returns a non-const reference to the appropriate storage.
+Of course the access to this storage must be ensured by the user. The library doesn't ensure the access to the internal storage is thread safe.
+
+There has been some work by the C++ standard committe on an `atomic_future` that behaves as an `atomic` variable, that is is thread_safe, 
+and a `shared_future` that can be shared between several threads, but there were not enough consensus and time to get it ready for C++11.       
+
+[endsect]
+
+[section:make_future Making immediate futures easier]
+
+Some functions may know the value at the point of construction. In these cases the value is immediately available, 
+but needs to be returned as a future or shared_future. By using make_future (make_shared_future) a future (shared_future) 
+can be created which holds a pre-computed result in its shared state.
+ 
+Without these features it is non-trivial to create a future directly from a value. 
+First a promise must be created, then the promise is set, and lastly the future is retrieved from the promise. 
+This can now be done with one operation.
+
+[heading make_future / make_shared_future]
+
+This function creates a future for a given value. If no value is given then a future<void> is returned. 
+This function is primarily useful in cases where sometimes, the return value is immediately available, but sometimes 
+it is not. The example below illustrates, that in an error path the value is known immediately, however in other paths 
+the function must return an eventual value represented as a future.
+
+
+  boost::future<int> compute(int x)
+  {
+    if (x == 0) return boost::make_future(0);
+    if (x < 0) return boost::make_future(-1);
+    boost::future<int> f1 = boost::async([]() { return x+1; });
+    return f1;
+  }
+  
+There are two variations of this function. The first takes a value of any type, and returns a future of that type. 
+The input value is passed to the shared state of the returned future. The second version takes no input and returns a future<void>.
+make_shared_future has the same functionality as make_future, except has a return type of shared_future.
+  
+
+[endsect]
+
+[section:then Associating future continuations]
+
+In asynchronous programming, it is very common for one asynchronous operation, on completion, to invoke a second 
+operation and pass data to it. The current C++ standard does not allow one to register a continuation to a future. 
+With .then, instead of waiting for the result, a continuation is "attached" to the asynchronous operation, which is 
+invoked when the result is ready. Continuations registered using the .then function will help to avoid blocking waits 
+or wasting threads on polling, greatly improving the responsiveness and scalability of an application.
+
+future.then provides the ability to sequentially compose two futures by declaring one to be the continuation of another. 
+With .then the antecedent future is ready (has a value or exception stored in the shared state) before the continuation 
+starts as instructed by the lambda function.
+
+In the example below the future<int> f2 is registered to be a continuation of future<int> f1 using the .then member 
+function. This operation takes a lambda function which describes how f2 should proceed after f1 is ready.
+
+
+  #include <boost/thread/future.hpp>
+  using namespace boost;
+  int main() 
+  {
+    future<int> f1 = async([]() { return 123; });
+    future<string> f2 = f1.then([](future<int> f) { return f.get().to_string(); // here .get() won't block });
+  }
+
+One key feature of this function is the ability to chain multiple asynchronous operations. In asynchronous programming, 
+it's common to define a sequence of operations, in which each continuation executes only when the previous one completes. 
+In some cases, the antecedent future produces a value that the continuation accepts as input. By using future.then, 
+creating a chain of continuations becomes straightforward and intuitive: 
+
+  myFuture.then(...).then(...).then(...). 
+  
+Some points to note are:
+
+* Each continuation will not begin until the preceding has completed.
+* If an exception is thrown, the following continuation can handle it in a try-catch block
+
+
+Input Parameters:
+
+* Lambda function2: One option which was considered was to follow JavaScript's approach and take two functions, one for 
+success and one for error handling. However this option is not viable in C++ as there is no single base type for 
+exceptions as there is in JavaScript. The lambda function takes a future as its input which carries the exception 
+through. This makes propagating exceptions straightforward. This approach also simplifies the chaining of continuations.
+* Scheduler: Providing an overload to .then, to take a scheduler reference places great flexibility over the execution 
+of the future in the programmer's hand. As described above, often taking a launch policy is not sufficient for powerful 
+asynchronous operations. The lifetime of the scheduler must outlive the continuation.
+* Launch policy: if the additional flexibility that the scheduler provides is not required.
+
+
+Return values: The decision to return a future was based primarily on the ability to chain multiple continuations using
+.then. This benefit of composability gives the programmer incredible control and flexibility over their code. Returning 
+a future object rather than a shared_future is also a much cheaper operation thereby improving performance. A 
+shared_future object is not necessary to take advantage of the chaining feature. It is also easy to go from a future 
+to a shared_future when needed using future::share().

+[section  Internal Locking]
+[note This tutorial is an adaptation of chapter Concurrency of the Object-Oriented Programming in the BETA Programming Language and  of the paper of Andrei Alexandrescu "Multithreading and the C++ Type System" to the Boost library.]
+[section Concurrent threads of execution]
+
+Consider, for example, modeling a bank account class that supports simultaneous deposits and withdrawals from multiple locations (arguably the "Hello, World" of multithreaded programming).
+
+From here a component is a model of the `Callable` concept.
+
+On C++11 (Boost) concurrent execution of a component is obtained by means of the `std::thread`(`boost::thread`):
+
+    boost::thread thread1(S);
+
+where `S` is a model of `Callable`. The meaning of this expression is that execution of `S()` will take place concurrently with the current thread of execution executing the expression.
+
+The following example includes a bank account of a person (Joe) and two components, one corresponding to a bank agent depositing money in Joe's account, and one representing Joe. Joe will only be withdrawing money from the account:
+
+  class BankAccount;
+
+  BankAccount JoesAccount;
+  
+  void bankAgent()
+  {
+      for (int i =10; i>0; --i) {
+          //...
+          JoesAccount.Deposit(500);
+          //...
+      }
+  }
+  
+  void Joe() {
+      for (int i =10; i>0; --i) {
+          //...
+          int myPocket = JoesAccount.Withdraw(100);
+          std::cout << myPocket << std::endl;
+          //...
+      }
+  }
+  
+  int main() {
+      //...
+      boost::thread thread1(bankAgent); // start concurrent execution of bankAgent
+      boost::thread thread2(Joe); // start concurrent execution of Joe
+      thread1.join();
+      thread2.join();
+      return 0;
+  }
+
+From time to time, the `bankAgent` will deposit $500 in `JoesAccount`. Joe will similarly withdraw $100 from his account. These sentences describe that the bankAgent and Joe are executed concurrently.
+
+The above example works well as long as the bankAgent and Joe doesn't access JoesAccount at the same time. There is, however, no guarantee that this will not happen. We may use a mutex to guarantee exclusive access to each bank.
+
+  class BankAccount {
+      boost::mutex mtx_;
+      int balance_;
+  public:
+      void Deposit(int amount) {
+          mtx_.lock();
+          balance_ += amount;
+          mtx_.unlock();
+      }
+      void Withdraw(int amount) {
+          mtx_.lock();
+          balance_ -= amount;
+          mtx_.unlock();
+      }
+      int GetBalance() {
+          mtx_.lock();
+          int b = balance_;
+          mtx_.unlock();
+          return balance_;
+      }
+  };
+
+Execution of the Deposit and Withdraw operations will no longer be able to make simultaneous access to balance.
+
+Mutex is a simple and basic mechanism for obtaining synchronization. In the above example it is relatively easy to be convinced that the synchronization works correctly (in the absence of exception). In a system with several concurrent objects and several shared objects, it may be difficult to describe synchronization by means of mutexes. Programs that make heavy use of mutexes may be difficult to read and write. Instead, we shall introduce a number of generic classes for handling more complicated forms of synchronization and communication.
+
+With the RAII idiom we can simplify a lot this using the scoped locks. In the code below, guard's constructor locks the passed-in object this, and guard's destructor unlocks this.
+
+  class BankAccount {
+      boost::mutex mtx_; // explicit mutex declaration 
+      int balance_;
+  public:
+      void Deposit(int amount) {
+          boost::lock_guard<boost::mutex> guard(mtx_);
+          balance_ += amount;
+      }
+      void Withdraw(int amount) {
+          boost::lock_guard<boost::mutex> guard(mtx_);
+          balance_ -= amount;
+      }
+      int GetBalance() {
+          boost::lock_guard<boost::mutex> guard(mtx_);
+          return balance_;
+      }
+  };
+
+The object-level locking idiom doesn't cover the entire richness of a threading model. For example, the model above is quite deadlock-prone when you try to coordinate multi-object transactions. Nonetheless, object-level locking is useful in many cases, and in combination with other mechanisms can provide a satisfactory solution to many threaded access problems in object-oriented programs.
+
+The BankAccount class above uses internal locking. Basically, a class that uses internal locking guarantees that any concurrent calls to its public member functions don't corrupt an instance of that class. This is typically ensured by having each public member function acquire a lock on the object upon entry. This way, for any given object of that class, there can be only one member function call active at any moment, so the operations are nicely serialized.
+
+This approach is reasonably easy to implement and has an attractive simplicity. Unfortunately, "simple" might sometimes morph into "simplistic."
+
+Internal locking is insufficient for many real-world synchronization tasks. Imagine that you want to implement an ATM withdrawal transaction with the BankAccount class. The requirements are simple. The ATM transaction consists of two withdrawals-one for the actual money and one for the $2 commission. The two withdrawals must appear in strict sequence; that is, no other transaction can exist between them.
+
+The obvious implementation is erratic:
+
+  void ATMWithdrawal(BankAccount& acct, int sum) {
+      acct.Withdraw(sum);
+      // preemption possible
+      acct.Withdraw(2);
+  }
+
+The problem is that between the two calls above, another thread can perform another operation on the account, thus breaking the second design requirement.
+
+In an attempt to solve this problem, let's lock the account from the outside during the two operations:
+
+  void ATMWithdrawal(BankAccount& acct, int sum) {
+      boost::lock_guard<boost::mutex> guard(acct.mtx_); 1
+      acct.Withdraw(sum);
+      acct.Withdraw(2);
+  }
+
+Notice that the code above doesn't compiles, the `mtx_` field is private.
+We have two possibilities:
+
+* make `mtx_` public which seams odd
+* make the `BankAccount` lockable by adding the lock/unlock functions
+
+We can add these functions explicitly
+
+  class BankAccount {
+      boost::mutex mtx_;
+      int balance_;
+  public:
+      void Deposit(int amount) {
+          boost::lock_guard<boost::mutex> guard(mtx_);
+          balance_ += amount;
+      }
+      void Withdraw(int amount) {
+          boost::lock_guard<boost::mutex> guard(mtx_);
+          balance_ -= amount;
+      }
+      void lock() {
+          mtx_.lock();
+      }
+      void unlock() {
+          mtx_.unlock();
+      }
+  };
+
+or inheriting from a class which add these lockable functions.
+
+The `basic_lockable_adapter` class helps to define the `BankAccount` class as
+
+  class BankAccount
+  : public basic_lockable_adapter<mutex>
+  {
+      int balance_;
+  public:
+      void Deposit(int amount) {
+          boost::lock_guard<BankAccount> guard(*this);
+          balance_ += amount;
+      }
+      void Withdraw(int amount) {
+          boost::lock_guard<BankAccount> guard(*this);
+          balance_ -= amount;
+      }
+      int GetBalance() {
+          boost::lock_guard<BankAccount> guard(*this);
+          return balance_;
+      }
+  };
+
+
+and the code that doesn't compiles becomes
+
+  void ATMWithdrawal(BankAccount& acct, int sum) {
+      boost::lock_guard<BankAccount> guard(acct);
+      acct.Withdraw(sum);
+      acct.Withdraw(2);
+  }
+
+Notice that now acct is being locked by Withdraw after it has already been locked by guard. When running such code, one of two things happens.
+
+* Your mutex implementation might support the so-called recursive mutex semantics. This means that the same thread can lock the same mutex several times successfully. In this case, the implementation works but has a performance overhead due to unnecessary locking. (The locking/unlocking sequence in the two Withdraw calls is not needed but performed anyway-and that costs time.)
+* Your mutex implementation might not support recursive locking, which means that as soon as you try to acquire it the second time, it blocks-so the ATMWithdrawal function enters the dreaded deadlock.
+
+As `boost::mutex` is not recursive, we need to use its recursive version `boost::recursive_mutex`.
+
+  class BankAccount
+  : public basic_lockable_adapter<recursive_mutex>
+  {
+  
+      // ...
+  };

+[section  Monitors]
+
+The use of `mutex` and `lockers`, as in `BankAccount`, is a common way of defining objects shared by two or more concurrent components. The basic_lockable_adapter class was a first step. 
+We shall therefore introduce an abstraction that makes it easier to define such objects. 
+The following class describes a so-called monitor pattern.
+
+  template <
+      typename Lockable=mutex
+  >
+  class basic_monitor : protected basic_lockable_adapter<Lockable> { // behaves like an BasicLockable for the derived classes 
+  protected:
+      typedef unspecified synchronizer; // is an strict lock guard 
+  };
+
+[/shared_monitor]
+[/monitor]
+
+A basic_monitor object behaves like a `BasicLockable` object but only for the inheriting classes. 
+Protected inheritance from lockable_adapter provide to all the derived classes all BasicLockable operations. In addition has a protected nested class, synchronizer, used when defining the monitor operations to synchronize the access critical regions. The BankAccount may be described using Monitor in the following way:
+
+  class BankAccount : protected basic_monitor<>
+  {
+  protected:
+      int balance_;
+  public:
+      BankAccount() : balance_(0) {}
+      BankAccount(const BankAccount &rhs) {
+          synchronizer _(*rhs.mutex());
+          balance_=rhs.balance_;
+      }
+  
+      BankAccount& operator=(BankAccount &rhs)
+      {
+          if(&rhs == this) return *this;
+  
+          int balance=0;
+          {
+              synchronizer _(*rhs.mutex());
+              balance=rhs.balance_;
+          }
+          synchronizer _(*this->mutex());
+          balance_=balance;
+          return *this;
+      }
+  
+      void Deposit(int amount) {
+          synchronizer _(*this->mutex());
+          balance_ += amount;
+      }
+      int Withdraw(int amount) {
+          synchronizer _(*this->mutex());
+          balance_ -= amount;
+          return amount;
+      }
+      int GetBalance() {
+          synchronizer _(*this->mutex());
+          return balance_;
+      }
+  };
+
+In the following, a monitor means some sub-class of monitor. A synchronized operation means an operation using the synchronizer guard defined within some monitor. Monitor is one example of a high-level concurrency abstraction that can be defined by means of mutexes.
+
+
+[section Monitor Conditions]
+
+It may happen that a component executing an entry operation of a monitor is unable to continue execution due to some condition not being fulfilled. Consider, for instance, a bounded buffer of characters. Such a buffer may be implemented as a monitor with two operations Push and Pull: the Puss operation cannot be executed if the buffer is full, and the Pull operation cannot be executed if the buffer is empty. A sketch of such a buffer monitor may look as
+follows:
+
+  class sync_buffer {
+      boost::mutex mtx_; 1
+  public:
+      ...
+      bool full() { return in_==out_; }
+      bool empty() { return in_==(out_%size)+1; }
+      void push(T& v) {
+          // wait if buffer is full
+          data_[in_]=v;
+          in_ = (in_% size)+1;
+      }
+      T pull() {
+          // wait if buffer is empty
+          out_ = (out_% size)+1;
+          return data_[out_];
+      }
+  };
+
+The meaning of a wait is that the calling component is delayed until the condition becomes true. We can do that using Boost.Thread condition variables like:
+
+  template <typename T, unsigned size>
+  class sync_buffer
+  {
+      typedef boost::mutex mutex_type;
+      typedef boost::condition_variable condition_type;
+      typedef boost::unique_lock<mutex_type> unique_lock_type;
+      mutex_type mtx_;
+      condition_type not_full_;
+      condition_type not_empty_;
+  
+      T data_[size+1];
+      unsigned in_, out_;
+  
+  public:
+      sync_buffer():in_(0), out_(0) {}
+  
+      bool full() { return out_==(in_+1)%(size+1); }
+      bool empty() { return out_==in_; }
+  
+      unsigned get_in() {return in_;}
+      unsigned get_out() {return out_;}
+      void push(T v) {
+          unique_lock_type guard(mtx_); 1
+          while (full()) { 2
+              not_full_.wait(guard);
+          }
+          data_[in_]=v;
+          in_ = (in_+1)% (size+1);
+          not_empty_.notify_one(); 3
+      }
+  
+      T pull() {
+          unique_lock_type guard(mtx_); 4
+          while (empty()) { 5
+              not_empty_.wait(guard);
+          }
+          unsigned idx = out_;
+          out_ = (out_+1)% (size+1);
+          not_full_.notify_one(); 6
+          return data_[idx];
+      }
+  };
+
+The Monitor class replace the nested synchronizer unique_lock with the class `condition_unique_lock` for this purpose:
+
+  template <
+      typename Lockable,
+      class Condition=condition_safe<typename best_condition<Lockable>::type >
+      , typename ScopeTag=typename scope_tag<Lockable>::type
+  >
+  class condition_unique_lock
+      : protected unique_lock<Lockable,ScopeTag>
+  {
+      BOOST_CONCEPT_ASSERT((LockableConcept<Lockable>));
+  public:
+      typedef Lockable lockable_type;
+      typedef Condition condition;
+  
+      explicit condition_unique_lock(lockable_type& obj); 1
+      condition_unique_lock(lockable_type& obj, condition &cond); 2
+      template <typename Predicate>
+      condition_unique_lock(lockable_type& obj, condition &cond, Predicate pred); 3
+      ~condition_unique_lock() 4
+  
+      typedef bool (condition_unique_lock::*bool_type)() const; 5
+      operator bool_type() const; 6
+      bool operator!() const { return false; } 7
+      bool owns_lock() const { return true; } 8
+      bool is_locking(lockable_type* l) const 9
+  
+      void relock_on(condition & cond);
+      template<typename Clock, typename Duration>
+      void relock_until(condition & cond, chrono::time_point<Clock, Duration> const& abs_time);
+      template<typename duration_type>
+      void relock_on_for(condition & cond, duration_type const& rel_time);
+  
+      template<typename Predicate>
+      void relock_when(condition &cond, Predicate pred);
+      template<typename Predicate>
+      template<typename Clock, typename Duration>
+      void relock_when_until(condition &cond, Predicate pred,
+              chrono::time_point<Clock, Duration> const& abs_time);
+      template<typename Predicate, typename duration_type>
+      void relock_when_for(condition &cond, Predicate pred,
+              duration_type const& rel_time);
+  
+      10
+  };
+
+
+We may now give the complete version of the buffer class. The content of the buffer is: `data_[out_+1], data_[out_+2], ... data_R[in_-1]` where all the indexes are modulo size. The buffer is full if `in_=out_` and it is empty if `in_=(out_+1)%size`.
+
+  template <typename T, unsigned size>
+  class sync_buffer : protected basic_monitor<>
+  {
+      condition not_full_;
+      condition not_empty_;
+  
+      T data_[size+1];
+      unsigned in_, out_;
+  
+      struct  not_full {
+          explicit not_full(sync_buffer &b):that_(b){};
+          bool operator()() const { return !that_.full(); }
+          sync_buffer &that_;
+      };
+      struct  not_empty {
+          explicit not_empty(sync_buffer &b):that_(b){};
+          bool operator()() const { return !that_.empty(); }
+          sync_buffer &that_;
+      };
+  public:
+      BOOST_COPY_CONSTRUCTOR_DELETE(sync_buffer) 1
+      BOOST_COPY_ASSIGNEMENT_DELETE(sync_buffer) 2
+      sync_buffer():in_(0), out_(0) {}
+  
+      bool full() { return out_==(in_+1)%(size+1); }
+      bool empty() { return out_==in_; }
+  
+      unsigned get_in() {return in_;}
+      unsigned get_out() {return out_;}
+  
+      void push(T v) {
+          synchronizer _(*this->mutex(), not_full_, not_full(*this)); 3
+          data_[in_]=v;
+          in_ = (in_+1)% (size+1);
+          not_empty_.notify_one(); 4
+      }
+  
+      T pull() {
+          synchronizer _(*this->mutex(), not_empty_, not_empty(*this)); 5
+          unsigned idx = out_;
+          out_ = (out_+1)% (size+1);
+          not_full_.notify_one(); 6
+          return data_[idx];
+      }
+  };
+
+Monitors and conditions are useful for describing simple cases of shared objects (by simple we mean a limited use of conditions). If the conditions for delaying a calling component become complicated, the monitor may similarly become difficult to program and read.

-        <h3>Motivation</h3>
-
-        <p>With client/server and three-tier architectures becoming common
-        place in today&#39;s world, it&#39;s becoming increasingly important
-        for programs to be able to handle parallel processing. Modern day
-        operating systems usually provide some support for this through native
-        thread APIs. Unfortunately, writing portable code that makes use of
-        parallel processing in C++ is made very difficult by a lack of a
-        standard interface for these native APIs. Further, these APIs are
-        almost universally C APIs and fail to take advantage of C++&#39;s
-        strengths, or to address C++&#39;s issues.</p>
-
-        <p>The <b>Boost.Threads</b> library is an attempt to define a portable
-        interface for writing parallel processes in C++.</p>
-
-        <h3>Goals</h3>
-
-        <p>The <b>Boost.Threads</b> library has several goals that should help
-        to set it apart from other solutions. These goals are listed in order
-        of precedence with full descriptions below.</p>
-
-        <ul>
-            <li>
-                <b>Portability</b> 
-
-                <p><b>Boost.Threads</b> was designed to be highly portable. The
-                goal is for the interface to be easily implemented on any
-                platform that supports threads, and possibly even on platforms
-                without native thread support.</p>
-            </li>
-
-            <li>
-                <b>Safety</b> 
-
-                <p><b>Boost.Threads</b> was designed to be as safe as possible.
-                Writing <a href="definitions.html#Thread-safe">thread-safe</a>
-                code is very difficult and successful libraries must strive to
-                insulate the programmer from dangerous constructs as much as
-                possible. This is accomplished in several ways:</p>
-
-                <ul>
-                    <li>
-                        <p align="left">C++ language features are used make
-                        correct usage easy (if possible, the default) and
-                        error-prone impossible or at least more difficult. For
-                        example, see the <a href="mutex_concept.html">Mutex</a>
-                        and <a href="lock_concept.html">Lock</a> designs, and
-                        how note how they interact.</p>
-                    </li>
-
-                    <li>
-                        <p align="left">Certain traditional concurrent
-                        programming features are considered so error-prone that
-                        they are not provided at all. For example, see the <a
-                        href="rationale.html#Events">Events Not Provided</a>
-                        rationale.</p>
-                    </li>
-
-                    <li>
-                        <p align="left">Dangerous features, or features which
-                        may be misused, are identified as such in the
-                        documentation to make users aware of potential
-                        pitfalls.</p>
-                    </li>
-                </ul>
-            </li>
-
-            <li>
-                <b>Flexibility</b> 
-
-                <p><b>Boost.Threads</b> was designed to be flexible. This goal
-                is often at odds with <i>safety</i>. When functionality might
-                be compromised by the desire to keep the interface safe, <b>
-                Boost.Threads</b> has been designed to provide the
-                functionality, but to make it&#39;s use prohibitive for general
-                use.</p>
-            </li>
-
-            <li>
-                <b>Efficiency</b> 
-
-                <p><b>Boost.Threads</b> was designed to be as efficient as
-                possible. When building a library on top of another library
-                there is always a danger that the result will be so much slower
-                than the &quot;native&quot; API that programmers are inclined
-                to ignore the higher level API. <b>Boost.Threads</b> was
-                designed to minimize the chances of this occurring. The
-                interfaces have been crafted to allow an implementation the
-                greatest chance of being as efficient as possible. This goal is
-                often at odds with the goal for <i>safety</i>. Every effort was
-                made to ensure efficient implementations, but when in conflict
-                <i>safety</i> has always taken precedence.</p>
-            </li>
-        </ul>
-
-        <h3>Iterative Phases</h3>
-
-        <p>Another goal of <b>Boost.Threads</b> was to take a dynamic,
-        iterative approach in its development. The computing industry is still
-        exploring the concepts of parallel programming. Most thread libraries
-        supply only simple primitive concepts for thread synchronization. These
-        concepts are very simple, but they are very difficult to use safely or
-        to provide formal proofs for constructs built on top of them. Until
-        recently, these primitives were &quot;state of the art&quot; and the
-        only concepts available to programmers. Recently there has been a lot
-        of research in other concepts, such as in &quot;Communicating
-        Sequential Processes.&quot; <b>Boost.Threads</b> was designed in
-        iterative steps, providing the building blocks necessary for the next
-        step, and giving the researcher the tools necessary to explore new
-        concepts in a portable manner.</p>
-
-        <p>Given the goal of following a dynamic, iterative approach <b>
-        Boost.Threads</b> shall go through several growth cycles. Each phase in
-        its development shall be roughly documented here.</p>
-
-        <h4>Phase 1, Synchronization Primitives</h4>

-        <p>Boost is all about providing high quality libraries with
-        implementations for many platforms. Unfortunately, there&#39;s a big
-        problem faced by developers wishing to supply such high quality
-        libraries, namely thread-safety. The C++ standard doesn&#39;t address
-        threads at all, but real world programs often make use of native
-        threading support. A portable library that doesn&#39;t address the
-        issue of thread-safety is there for not much help to a programmer who
-        wants to use the library in his multi-threaded application. So
-        there&#39;s a very great need for portable primitives that will allow
-        the library developer to create <a href="definitions.html#Thread-safe">
-        thread-safe</a> implementations. This need far out weighs the need for
-        portable methods to create and manage threads.</p>
-
-        <p>Because of this need, the first phase of <b>Boost.Threads</b>
-        focuses solely on providing portable primitive concepts for thread
-        synchronization. Types provided in this phase include the <a href="mutex.html">
-        mutex/try_mutex/timed_mutex</a>, <a href="recursive_mutex.html">
-        recursive_mutex/recursive_try_mutex/recursive_timed_mutex</a>, <a href=
-        "scoped_lock.html">scoped_lock</a>, <a href="scoped_try_lock.html">
-        scoped_try_lock</a>, <a href="scoped_timed_lock.html">
-        scoped_timed_lock</a> and <a href="lock_error.html">lock_error</a>.
-        These are considered the &quot;core&quot; synchronization primitives,
-        though there are others that will be added in later phases.</p>
-
-        <h4>Phase 2, Thread Management and Thread Specific Storage</h4>
-
-        <p>This phase addresses the creation and management of threads and
-        provides a mechanism for thread specific storage (data associated with
-        a thread instance). Thread management is a tricky issue in C++, so this
-        phase addresses only the basic needs of multi-threaded program. Later
-        phases are likely to add additional functionality in this area. This
-        phase of <b>Boost.Threads</b> adds the <a href="thread.html">thread</a>
-        and <a href="thread_specific_ptr.html">thread_specific_ptr</a> types.
-        With these additions the <b>Boost.Threads</b> library can be considered
-        minimal but complete.</p>
-
-        <h4>The Next Phase</h4>
-
-        <p>The next phase will address more advanced synchronization concepts,
-        such as read/write mutexes and barriers.</p>

-        <h2><a name="Introduction">Introduction</a></h2>
-
-        <p>The lock concepts provide exception safe means for locking and
-        unlocking a <a href="mutex_concept.html">mutex model</a>. In other
-        words they are an implementation of the <i>Scoped Locking</i> <a href=
-        "bibliography.html#Schmidt 00">[Schmidt 00]</a> pattern. The <a href=
-        "#ScopedLock">ScopedLock</a> concept, with <a href="#ScopedTryLock">
-        ScopedTryLock</a> and <a href="#ScopedTimedLock">ScopedTimedLock</a>
-        refinements, formalize the requirements.</p>
-
-        <p>Lock models are constructed with a reference to a <a href=
-        "mutex_concept.html">mutex model</a> and typically acquire ownership of
-        the <a href="mutex_concept.html">mutex model</a> by setting its state
-        to locked. They also ensure ownership is relinquished in the
-        destructor. Lock models also expose functions to query the lock status
-        and to manually lock and unlock the <a href="mutex_concept.html">mutex
-        model</a>.</p>
-
-        <p>Instances of lock models are meant to be short lived, expected to be
-        used at block scope only. The lock models are not <a href=
-        "definitions.html#Thread-safe">thread-safe</a>. Lock models must
-        maintain state to indicate whether or not they&#39;ve been locked and
-        this state is not protected by any synchronization concepts. For this
-        reason an instance of a lock model should never be shared between
-        multiple threads.</p>
-
-        <h2>Concept <a name="Requirements">Requirements</a></h2>
-
-        <p>[For documentation purposes, portions of the concept requirements
-        are repeated in the documentation for specific lock classes. Those
-        copies need to be kept in sync with the requirements here.]</p>

-        and const object <code>clk</code> of that type, the following
-        expressions must be well-formed and have the indicated effects.</p>
-
-        <p>The Lock concept is used as a base for the <a href="#ScopedLock">
-        ScopedLock</a>, <a href="#ScopedTryLock">ScopedTryLock</a>, and <a
-        href="#ScopedTimedLock">ScopedTimedLock</a> refinements. The associated

-        <h2><a name="Introduction">Introduction</a></h2>
-
-        <p>A mutex (short for mutual-exclusion) concept serializes access to a
-        resource shared between multiple threads. The <a href="#Mutex">
-        Mutex</a> concept, with <a href="#TryMutex">TryMutex</a> and <a href=
-        "#TimedMutex">TimedMutex</a> refinements, formalize the requirements. A
-        model that implements Mutex and its refinements has two states: <b>
-        locked</b> and <b>unlocked</b>. Before using a shared resource, a
-        thread locks a Boost.Threads mutex model object, insuring <a href=
-        "definitions.html#Thread-safe">thread-safe</a> access to the shared
-        resource. When use of the shared resource is complete, the thread
-        unlocks the mutex model object, allowing another thread to acquire the
-        lock and use the shared resource.</p>
-
-        <p>Traditional C thread APIs, like Pthreads or the Windows thread APIs,
-        expose functions to lock and unlock a mutex model. This is dangerous
-        since it&#39;s easy to forget to unlock a locked mutex. When the flow
-        of control is complex, with multiple return points, the likelihood of
-        forgetting to unlock a mutex model would become even greater. When
-        exceptions are thrown, it becomes nearly impossible to ensure that the
-        mutex is unlocked properly when using these traditional API&#39;s. The
-        result is <a href="definitions.html#Deadlock">deadlock</a>.</p>
-
-        <p>Many C++ threading libraries use a pattern known as <i>Scoped
-        Locking</i> <a href="bibliography.html#Schmidt 00">[Schmidt 00]</a> to
-        free the programmer from the need to explicitly lock and unlock
-        mutexes. With this pattern, a <a href="lock_concept.html">lock
-        concept</a> is employed where the lock model&#39;s constructor locks
-        the associated mutex model and the destructor automatically does the
-        unlocking. The <b>Boost.Threads</b> library takes this pattern to the
-        extreme in that lock concepts are the only way to lock and unlock a
-        mutex model: lock and unlock functions are not exposed by any <b>
-        Boost.Threads</b> mutex models. This helps to ensure safe usage
-        patterns, especially when code throws exceptions.</p>
-
-        <h2><a name="LockingStrategies">Locking Strategies</a></h2>
-
-        <p>Every mutex model follows one of several locking strategies. These
-        strategies define the semantics for the locking operation when the
-        calling thread already owns a lock on the mutex model.</p>
-
-        <h3><a name="Recursive">Recursive</a></h3>
-
-        <p>With a recursive locking strategy when a thread attempts to acquire
-        a lock on the mutex model for which it already owns a lock, the
-        operation is successful. Note the distinction between a thread, which
-        may have multiple locks outstanding on a recursive mutex, and a lock
-        object, which even for a recursive mutex cannot have its lock()
-        function called multiple times without first calling unlock().</p>
-
-        <p>Internally a lock count is maintained and the owning thread must
-        unlock the mutex model the same number of times that it&#39;s locked it
-        before the mutex model&#39;s state returns to unlocked. Since mutex
-        models in <b>Boost.Threads</b> expose locking functionality only
-        through lock concepts, a thread will always unlock a mutex model the
-        same number of times that it locked it. This helps to eliminate a whole
-        set of errors typically found in traditional C style thread APIs.</p>
-
-        <p>Classes <a href="recursive_mutex.html">recursive_mutex</a>, <a href=
-        "recursive_mutex.html">recursive_try_mutex</a> and <a href=
-        "recursive_mutex.html">recursive_timed_mutex</a> use this locking
-        strategy.</p>
-
-        <h3><a name="CheckedStrategy">Checked</a></h3>
-
-        <p>With a checked locking strategy when a thread attempts to acquire a
-        lock on the mutex model for which the thread already owns a lock, the
-        operation will fail with some sort of error indication. Further,
-        attempts by a thread to unlock a mutex that was not locked by the
-        thread will also return some sort of error indication. In <b>
-        Boost.Threads</b>, an exception of type <a href="lock_error.html">
-        lock_error</a> would be thrown in these cases.</p>
-
-        <p><b>Boost.Threads</b> does not currently provide any mutex models
-        that use this strategy.</p>
-
-        <h3><a name="UncheckedStrategy">Unchecked</a></h3>
-
-        <p>With an unchecked locking strategy when a thread attempts to acquire
-        a lock on the mutex model for which the thread already owns a lock the
-        operation will <a href="definitions.html#Deadlock">deadlock</a>. In
-        general this locking strategy is less safe than a checked or recursive
-        strategy, but it&#39;s also a faster strategy and so is employed by
-        many libraries.</p>
-
-        <p><b>Boost.Threads</b> does not currently provide any mutex models
-        that use this strategy.</p>
-
-        <h3><a name="UnspecifiedStrategy">Unspecified</a></h3>
-
-        <p>With an unspecified locking strategy, when a thread attempts to
-        acquire a lock on a mutex model for which the thread already owns a
-        lock the operation results in <b>undefined behavior</b>. When a mutex
-        model has an unspecified locking strategy the programmer must assume
-        that the mutex model instead uses an unchecked strategy.</p>
-
-        <p>In general a mutex model with an unspecified locking strategy is
-        unsafe, and it requires programmer discipline to use the mutex model
-        properly. However, this strategy allows an implementation to be as fast
-        as possible with no restrictions on its implementation. This is
-        especially true for portable implementations that wrap the native
-        threading support of a platform. For this reason, the classes <a href=
-        "mutex.html">mutex</a>, <a href="mutex.html">try_mutex</a> and <a href=
-        "mutex.html">timed_mutex</a> use this locking strategy despite the lack
-        of safety.</p>
-
-        <h2><a name="SchedulingPolicies">Scheduling Policies</a></h2>
-
-        <p>Every mutex model follows one of several scheduling policies. These
-        policies define the semantics when the mutex model is unlocked and
-        there is more than one thread waiting to acquire a lock. In other
-        words, the policy defines which waiting thread shall acquire the
-        lock.</p>
-
-        <h3><a name="FIFO">FIFO</a></h3>
-
-        <p>With a FIFO scheduling policy, threads waiting for the lock will
-        acquire it in a first come first serve order (or First In First Out).
-        This can help prevent a high priority thread from starving lower
-        priority threads that are also waiting on the mutex lock.</p>
-
-        <h3><a name="Priority Driven">Priority Driven</a></h3>
-
-        <p>With a Priority Driven scheduling policy, the thread with the
-        highest priority acquires the lock. Note that this means that
-        low-priority threads may never acquire the lock if the mutex model has
-        high contention and there is always at least one high-priority thread
-        waiting. This is known as thread starvation. When multiple threads of
-        the same priority are waiting on the mutex lock one of the other
-        scheduling priorities will determine which thread shall acquire the
-        lock.</p>
-
-        <h3><a name="UndefinedScheduling">Undefined</a></h3>
-
-        <p>Threads acquire the lock in no particular order. Users should assume
-        that low-priority threads may wait indefinitely, and that threads of
-        the same priority acquire the lock in essentially random order.</p>
-
-        <h3><a name="UnspecifiedScheduling">Unspecified</a></h3>
-
-        <p>The mutex model does not specify which scheduling policy is used.
-        The programmer must assume that an undefined scheduling policy is used.
-        In order to ensure portability, all <b>Boost.Threads</b> mutex models
-        use an unspecified scheduling policy.</p>

-        <h2><a name="Introduction">Introduction</a></h2>
-
-        <p>Boost.Threads allows C++ programs to execute as multiple,
-        asynchronous, independent, threads-of-execution. Each thread has its
-        own machine state including program instruction counter and registers.
-        Programs which execute as multiple threads are called multi-threaded
-        programs to distinguish them from traditional single-threaded programs.
-        <a href="definitions.html">Definitions</a> gives a more complete
-        description of the multi-threading execution environment.</p>
-
-        <p>Multi-threading provides several advantages:</p>
-
-        <ul>
-            <li>Programs which would otherwise block waiting for some external
-            event can continue to respond if the blocking operation is placed
-            in a separate thread. Multi-threading is usually an absolute
-            requirement for these programs.</li>
-        </ul>
-
-        <ul>
-            <li>Well-designed multi-threaded programs may execute faster than
-            single-threaded programs, particularly on multi-processor hardware.
-            Note, however, that poorly-designed multi-threaded programs are
-            often slower that single-threaded programs.</li>
-        </ul>
-
-        <ul>
-            <li>Some program designs may be easier to formulate using a
-            multi-threaded approach. After all, the real world is
-            asynchronous!</li>
-        </ul>
-
-        <h2><a name="Dangers">Dangers</a></h2>
-
-        <p>Beyond the errors which can occur in single-threaded programs,
-        multi-threaded programs are subject to additional errors:</p>
-
-        <ul>
-            <li><a href="definitions.html#Race condition">Race
-            conditions</a>.</li>
-
-            <li><a href="definitions.html#Deadlock">Deadlock</a> (sometimes
-            called &quot;deadly embrace&quot;)</li>
-
-            <li><a href="definitions.html#Priority failure">Priority
-            failures</a> (priority inversion, infinite overtaking, starvation,
-            etc.)</li>
-        </ul>
-
-        <p>Every multi-threaded program must be designed carefully to avoid
-        race conditions and deadlock. These aren&#39;t rare or exotic failures
-        - they are virtually guaranteed to occur unless multi-threaded code is
-        designed to avoid them. Priority failures are somewhat less common, but
-        are none-the-less serious.</p>
-
-        <p>The <a href="introduction.html">Boost.Threads design</a> attempts to
-        minimize these errors, but they will still occur unless the programmer
-        proactively designs to avoid them.</p>
-
-        <h3>Testing and debugging considerations</h3>
-
-        <p>Multi-threaded programs are non-deterministic. In other words, the
-        same program with the same input data may follow different execution
-        paths each time it is invoked. That can make testing and debugging a
-        nightmare:</p>
-
-        <ul>
-            <li>Failures are often not repeatable.</li>
-
-            <li>Probe effect causes debuggers to produce very different results
-            from non-debug uses.</li>
-
-            <li>Debuggers require special support to show thread state.</li>
-
-            <li>Tests on a single processor system may give no indication of
-            serious errors which would appear on multiprocessor systems, and
-            visa versa. Thus test cases should include a varying number of
-            processors.</li>
-
-            <li>For programs which create a varying number of threads according
-            to workload, tests which don&#39;t span the full range of
-            possibilities may miss serious errors.</li>
-        </ul>
-
-        <h3>Getting a head start</h3>
-
-        <p>Although it might appear that multi-threaded programs are inherently
-        unreliable, many reliable multi-threaded programs do exist.
-        Multi-threading techniques are known which lead to reliable
-        programs.</p>
-
-        <p>Design patterns for reliable multi-threaded programs, including the
-        important <i>monitor</i> pattern, are presented in <cite>
-        Pattern-Oriented Software Architecture Volume 2 - Patterns for
-        Concurrent and Networked Objects</cite> [<a href=
-        "bibliography.html#Schmidt-00">Schmidt 00</a>]. Many important
-        multi-threading programming considerations (independent of threading
-        library) are discussed in <cite>Programming with POSIX Threads</cite>
-        [<a href="bibliography.html#Butenhof-97">Butenhof 97</a>].</p>
-
-        <p>Doing some reading before attempting multi-threaded designs will give
-        you a head start toward reliable multi-threaded programs.</p>
-
-        <h2><a name="Library">C++ Standard Library usage in multi-threaded
-        programs</a></h2>
-
-        <h3>Runtime libraries</h3>
-
-        <p><b>Warning:</b> Multi-threaded programs such as those using <b>
-        Boost.Threads</b> must link to <a href="definitions.html#Thread-safe">
-        thread-safe</a> versions of all runtime libraries used by the program,
-        including the runtime library for the C++ Standard Library. Otherwise
-        <a href="definitions.html#Race condition">race conditions</a> will
-        occur when multiple threads simultaneously execute runtime library
-        functions for <i>new</i>, <i>delete</i>, or other language features
-        which imply shared state.</p>
-
-        <h3>Potentially non-thread-safe functions</h3>
-
-        <p>Certain C++ Standard Library functions inherited from C are
-        particular problems because they hold internal state between calls:</p>
-
-        <ul>
-            <li>rand</li>
-
-            <li>strtok</li>
-
-            <li>asctime</li>
-
-            <li>ctime</li>
-
-            <li>gmtime</li>
-
-            <li>localtime</li>
-        </ul>
-
-        <p>It is possible to write thread-safe implementations of these by
-        using <a href="thread_specific_ptr.html">thread-specific storage</a>,
-        and several C++ compiler vendors do just that. The technique is
-        well-know and is explained in [<a href=
-        "bibliography.html#Butenhof-97">Buttenhof-97</a>].</p>
-
-        <p>But at least one vendor (HP-UX) does not provide thread-safe
-        implementations of the above functions in their otherwise thread-safe
-        runtime library. Instead they provide replacement functions with
-        different names and arguments.</p>
-
-        <p><b>Recommendation:</b> For the most portable, yet thread-safe code,
-        use Boost replacements for the problem functions. See the <a href=
-        "../../random/index.html">Boost Random Number Library</a> and <a href=
-        "../../tokenizer/index.htm">Boost Tokenizer Library</a>.</p>
-
-        <h2><a name="Common">Common</a> requirements for all Boost.Threads
-        components</h2>
-
-        <h3>Exceptions</h3>
-
-        <p><b>Boost.Threads</b> destructors never throw exceptions. Unless
-        otherwise specified, other <b>Boost.Threads</b> functions that do not
-        have an exception-specification may throw implementation-defined
-        exceptions.</p>
-
-        <p>In particular, <b>Boost.Threads</b> reports failure to allocate
-        storage by throwing an exception of type std::bad_alloc, or a class
-        derived from std::bad_alloc, failure to obtain thread resources other
-        than memory by throwing an exception of type <a href=
-        "thread_resource_error.html">boost::thread_resource_error</a>, and
-        certain lock related failures by throwing an exception of type <a href=
-        "lock_error.html">boost::lock_error</a></p>
-
-        <p><b>Rationale:</b> Follows the C++ Standard Library practice of
-        allowing all functions except destructors or other specified functions
-        to throw exceptions on errors.</p>
-
-        <h3><a name="NonCopyable">NonCopyable</a> requirement</h3>
-
-        <p><b>Boost.Threads</b> classes documented as meeting the NonCopyable
-        requirement disallow copy construction and copy assignment. For the
-        sake of exposition, the synopsis of such classes show private
-        derivation from <a href="../../utility/utility.htm">
-        boost::noncopyable</a>. Users should not depend on this derivation,
-        however, as implementations are free to meet the NonCopyable
-        requirement in other ways.</p>

+
+Anthony Williams version (version 2) was a major rewrite designed to
+closely follow the proposals presented to the C++ Standards Committee, in particular

+Some minor non-standard features have been added also as thread attributes, reverse_lock, shared_lock_guard.
+
+In order to use the classes and functions described here, you can
+either include the specific headers specified by the descriptions of

+
+which includes all the other headers in turn.
+
+[endsect]
+
+
+[section:build Using and building the library]
+
+Boost.Thread is configured following the conventions used to build [@http://www.boost.org/doc/libs/1_48_0/libs/config/doc/html/boost_config/boost_macro_reference.html#boost_config.boost_macro_reference.macros_for_libraries_with_separate_source_code libraries with separate source code]. Boost.Thread will import/export the code only if the user has specifically asked for it, by defining either BOOST_ALL_DYN_LINK if they want all boost libraries to be dynamically linked, or BOOST_THREAD_DYN_LINK if they want just this one to be dynamically liked.
+
+The definition of these macros determines whether BOOST_THREAD_USE_DLL is defined. If  BOOST_THREAD_USE_DLL is not defined, the library will define BOOST_THREAD_USE_DLL or BOOST_THREAD_USE_LIB depending on whether the platform. On non windows platforms BOOST_THREAD_USE_LIB is defined if is not defined. In windows platforms, BOOST_THREAD_USE_LIB is defined if BOOST_THREAD_USE_DLL and the compiler supports auto-tss cleanup with Boost.Threads (for the time been Msvc and Intel)
+
+The source code compiled when building the library defines a macros BOOST_THREAD_SOURCE that is used to import or export it. The user must not define this macro in any case. 
+
+Boost.Thread depends on some non header-only libraries. 
+
+* Boost.System: This dependency is mandatory and you will need to link with the library.
+
+* Boost.Chrono: This dependency is optional (see below how to configure) and you will need to link with the library if you use some of the time related interfaces.
+
+* Boost.DateTime: This dependency is mandatory, but even if Boost.DateTime is a non header-only library Boost.Thread uses only parts that are header-only, so in principle you should not need to link with the library. 
+
+It seems that there are some IDE (as e.g. Visual Studio) that deduce the libraries that a program needs to link to inspecting the sources. Such IDE could force to link to Boost.DateTime and/or Boost.Chrono.
+
+As the single mandatory dependency is to Boost.System, the following
+
+  bjam toolset=msvc-11.0 --build-type=complete --with-thread 
+
+will install only boost_thread and boost_system. 
+
+Users of such IDE should force the Boost.Chrono and Boost.DateTime build using 
+
+  bjam toolset=msvc-11.0 --build-type=complete --with-thread --with-chrono --with-date_time 
+
+
+The following section describes all the macros used to configure Boost.Thread.

-
-        <p>This page explains the rationale behind various design decisions in
-        the <b>Boost.Threads</b> library. Having the rationale documented here
-        should explain how we arrived at the current design as well as prevent
-        future rehashing of discussions and thought processes that have already
-        occurred. It can also give users a lot of insight into the design
-        process required for this library.</p>
-
-        <h2><a name="library">Rationale for the Creation of
-        Boost.Threads</a></h2>
-
-        <p>Processes often have a degree of &quot;potential parallelism&quot;
-        and it can often be more intuitive to design systems with this in mind.
-        Further, these parallel processes can result in more responsive
-        programs. The benefits for multi-threaded programming are quite well
-        known to most modern programmers, yet the C++ language doesn&#39;t
-        directly support this concept.</p>
-
-        <p>Many platforms support multi-threaded programming despite the fact
-        that the language doesn&#39;t support it. They do this through external
-        libraries, which are, unfortunately, platform specific. POSIX has tried
-        to address this problem through the standardization of a
-        &quot;pthread&quot; library. However, this is a standard only on POSIX
-        platforms, so its portability is limited.</p>
-
-        <p>Another problem with POSIX and other platform specific thread
-        libraries is that they are almost universally C based libraries. This
-        leaves several C++ specific issues unresolved, such as what happens
-        when an exception is thrown in a thread. Further, there are some C++
-        concepts, such as destructors, that can make usage much easier than
-        what&#39;s available in a C library.</p>
-
-        <p>What&#39;s truly needed is C++ language support for threads.
-        However, the C++ standards committee needs existing practice or a good
-        proposal as a starting point for adding this to the standard.</p>
-
-        <p>The Boost.Threads library was developed to provide a C++ developer
-        with a portable interface for writing multi-threaded programs on
-        numerous platforms. There&#39;s a hope that the library can be the
-        basis for a more detailed proposal for the C++ standards committee to
-        consider for inclusion in the next C++ standard.</p>
-
-        <h2><a name="primitives">Rationale for the Low Level Primitives
-        Supported in Boost.Threads</a></h2>
-
-        <p>The Boost.Threads library supplies a set of low level primitives for
-        writing multi-threaded programs, such as mutexes and condition variables.
-        In fact, the first release of Boost.Threads supports only these low level
-        primitives. However, computer science research has shown that use of these
-        primitives is difficult since there&#39;s no way to mathematically prove
-        that a usage pattern is correct, meaning it doesn&#39;t result in race
-        conditions or deadlocks. There are several algebras (such as CSP, CCS and
-        Join calculus) that have been developed to help write provably correct
-        parallel processes. In order to prove the correctness these processes must
-        be coded using higher level abstractions. So why does Boost.Threads support
-        the lower level concepts?</p>
-
-        <p>The reason is simple: the higher level concepts need to be
-        implemented using at least some of the lower level concepts. So having
-        portable lower level concepts makes it easier to develop the higher
-        level concepts and will allow researchers to experiment with various
-        techniques.</p>
-
-        <p>Beyond this theoretical application of higher level concepts,
-        however, the fact remains that many multi-threaded programs are written
-        using only the lower level concepts, so they are useful in and of
-        themselves, even if it&#39;s hard to prove that their usage is correct.
-        Since many users will be familiar with these lower level concepts but
-        be unfamiliar with any of the higher level concepts there&#39;s also an

-        <h2><a name="lock_objects">Rationale for the Lock Design</a></h2>
-
-        <p>Programmers who are used to multi-threaded programming issues will
-        quickly note that the Boost.Thread&#39;s design for mutex lock concepts
-        is not <a href="definitions.html#Thread-safe">thread-safe</a> (this is
-        clearly documented as well). At first this may seem like a serious
-        design flaw. Why have a multi-threading primitive that&#39;s not
-        thread-safe itself?</p>
-
-        <p>A lock object is not a synchronization primitive. A lock
-        object&#39;s sole responsibility is to ensure that a mutex is both
-        locked and unlocked in a manner that won&#39;t result in the common
-        error of locking a mutex and then forgetting to unlock it. This means
-        that instances of a lock object are only going to be created, at least
-        in theory, within block scope and won&#39;t be shared between threads.
-        Only the mutex objects will be created outside of block scope and/or
-        shared between threads. Though it&#39;s possible to create a lock
-        object outside of block scope and to share it between threads to do so
-        would not be a typical usage. Nor are there any cases when such usage
-        would be required.</p>
-
-        <p>Lock objects must maintain some state information. In order to allow
-        a program to determine if a try_lock or timed_lock was successful the
-        lock object must retain state indicating the success or failure of the
-        call made in its constructor. If a lock object were to have such state
-        and remain thread-safe it would need to synchronize access to the state
-        information which would result in roughly doubling the time of most
-        operations. Worse, since checking the state can occur only by a call
-        after construction we&#39;d have a race condition if the lock object
-        were shared between threads.</p>
-
-        <p>So, to avoid the overhead of synchronizing access to the state
-        information and to avoid the race condition the Boost.Threads library
-        simply does nothing to make lock objects thread-safe. Instead, sharing
-        a lock object between threads results in undefined behavior. Since the
-        only proper usage of lock objects is within block scope this isn&#39;t
-        a problem, and so long as the lock object is properly used there&#39;s
-        no danger of any multi-threading issues.</p>
-
-        <h2><a name="thread">Rationale for Non-copyable Thread Type</a></h2>
-
-        <p>Programmers who are used to C libraries for multi-threaded
-        programming are likely to wonder why Boost.Threads uses a non-copyable
-        design for <a href="thread.html">boost::thread</a>. After all, the C
-        thread types are copyable, and you often have a need for copying them
-        within user code. However, careful comparison of C designs to C++
-        designs shows a flaw in this logic.</p>
-
-        <p>All C types are copyable. It is, in fact, not possible to make a
-        non-copyable type in C. For this reason types that represent system
-        resources in C are often designed to behave very similarly to a pointer
-        to dynamic memory. There&#39;s an API for acquiring the resource and an
-        API for releasing the resources. For memory we have pointers as the
-        type and alloc/free for the acquisition and release APIs. For files we
-        have FILE* as the type and fopen/fclose for the acquisition and release
-        APIs. You can freely copy instances of the types but must manually
-        manage the lifetime of the actual resource through the acquisition and
-        release APIs.</p>
-
-        <p>C++ designs recognize that the acquisition and release APIs are
-        error prone and try to eliminate possible errors by acquiring the
-        resource in the constructor and releasing it in the destructor. The
-        best example of such a design is the std::iostream set of classes which
-        can represent the same resource as the FILE* type in C. A file is
-        opened in the std::fstream&#39;s constructor and closed in its
-        destructor. However, if an iostream were copyable it could lead to a
-        file being closed twice, an obvious error, so the std::iostream types
-        are noncopyable by design. This is the same design used by
-        boost::thread, which is a simple and easy to understand design
-        that&#39;s consistent with other C++ standard types.</p>
-
-        <p>During the design of boost::thread it was pointed out that it would
-        be possible to allow it to be a copyable type if some form of
-        &quot;reference management&quot; were used, such as ref-counting or
-        ref-lists, and many argued for a boost::thread_ref design instead. The
-        reasoning was that copying &quot;thread&quot; objects was a typical
-        need in the C libraries, and so presumably would be in the C++
-        libraries as well. It was also thought that implementations could
-        provide more efficient reference management then wrappers (such as
-        boost::shared_ptr) around a noncopyable thread concept. Analysis of
-        whether or not these arguments would hold true don&#39;t appear to bear
-        them out. To illustrate the analysis we&#39;ll first provide
-        pseudo-code illustrating the six typical usage patterns of a thread
-        object.</p>
-
-        <h3>1. Simple creation of a thread.</h3>
-<pre>
-void foo()
-{
-   create_thread(&amp;bar);
-}
-</pre>
-
-        <h3>2. Creation of a thread that&#39;s later joined.</h3>
-<pre>
-void foo()
-{
-   thread = create_thread(&amp;bar);
-   join(thread);
-}
-</pre>
-
-        <h3>3. Simple creation of several threads in a loop.</h3>
-<pre>
-void foo()
-{
-   for (int i=0; i&lt;NUM_THREADS; ++i)
-      create_thread(&amp;bar);
-}
-</pre>
-
-        <h3>4. Creation of several threads in a loop which are later
-        joined.</h3>
-<pre>
-void foo()
-{
-   for (int i=0; i&lt;NUM_THREADS; ++i)
-      threads[i] = create_thread(&amp;bar);
-   for (int i=0; i&lt;NUM_THREADS; ++i)
-      threads[i].join();
-}
-</pre>
-
-        <h3>5. Creation of a thread whose ownership is passed to another
-        object/method.</h3>
-<pre>
-void foo()
-{
-   thread = create_thread(&amp;bar);
-   manager.owns(thread);
-}
-</pre>
-
-        <h3>6. Creation of a thread whose ownership is shared between multiple
-        objects.</h3>
-<pre>
-void foo()
-{
-   thread = create_thread(&amp;bar);
-   manager1.add(thread);
-   manager2.add(thread);
-}
-</pre>
-
-        <p>Of these usage patterns there&#39;s only one that requires reference
-        management (number 6). Hopefully it&#39;s fairly obvious that this
-        usage pattern simply won&#39;t occur as often as the other usage
-        patterns. So there really isn&#39;t a &quot;typical need&quot; for a
-        thread concept, though there is some need.</p>
-
-        <p>Since the need isn&#39;t typical we must use different criteria for
-        deciding on either a thread_ref or thread design. Possible criteria
-        include ease of use and performance. So let&#39;s analyze both of these
-        carefully.</p>
-
-        <p>With ease of use we can look at existing experience. The standard
-        C++ objects that represent a system resource, such as std::iostream,
-        are noncopyable, so we know that C++ programmers must at least be
-        experienced with this design. Most C++ developers are also used to
-        smart pointers such as boost::shared_ptr, so we know they can at least
-        adapt to a thread_ref concept with little effort. So existing
-        experience isn&#39;t going to lead us to a choice.</p>
-
-        <p>The other thing we can look at is how difficult it is to use both
-        types for the six usage patterns above. If we find it overly difficult
-        to use a concept for any of the usage patterns there would be a good
-        argument for choosing the other design. So we&#39;ll code all six usage
-        patterns using both designs.</p>

-void foo()
-{
-   thread_ref thrd = create_thread(&amp;bar);
-   manager1.add(thrd);
-   manager2.add(thrd);
-}
-</pre>
-
-        <p>This shows the usage patterns being nearly identical in complexity
-        for both designs. The only actual added complexity occurs because of
-        the use of operator new in (4), (5) and (6) and the use of
-        std::auto_ptr and boost::shared_ptr in (4) and (6) respectively.
-        However, that&#39;s not really much added complexity, and C++
-        programmers are used to using these idioms any way. Some may dislike
-        the presence of operator new in user code, but this can be eliminated
-        by proper design of higher level concepts, such as the
-        boost::thread_group class that simplifies example (4) down to:</p>
-<pre>
-void foo()
-{
-   thread_group threads;
-   for (int i=0; i&lt;NUM_THREADS; ++i)
-      threads.create_thread(&amp;bar);
-   threads.join_all();
-}
-</pre>
-
-        <p>So ease of use is really a wash and not much help in picking a
-        design.</p>
-
-        <p>So what about performance? If you look at the above code examples we
-        can analyze the theoretical impact to performance that both designs
-        have. For (1) we can see that platforms that don&#39;t have a
-        ref-counted native thread type (POSIX, for instance) will be impacted
-        by a thread_ref design. Even if the native thread type is ref-counted
-        there may be an impact if more state information has to be maintained
-        for concepts foreign to the native API, such as clean up stacks for
-        Win32 implementations. For (2) the performance impact will be identical
-        to (1). The same for (3). For (4) things get a little more interesting
-        and we find that theoretically at least the thread_ref may perform
-        faster since the thread design requires dynamic memory
-        allocation/deallocation. However, in practice there may be dynamic
-        allocation for the thread_ref design as well, it will just be hidden
-        from the user. As long as the implementation has to do dynamic
-        allocations the thread_ref loses again because of the reference
-        management. For (5) we see the same impact as we do for (4). For (6) we
-        still have a possible impact to the thread design because of dynamic
-        allocation but thread_ref no longer suffers because of it&#39;s
-        reference management, and in fact, theoretically at least, the
-        thread_ref may do a better job of managing the references. All of this
-        indicates that thread wins for (1), (2) and (3), with (4) and (5) the
-        winner depends on the implementation and the platform but the thread
-        design probably has a better chance, and with (6) it will again depend
-        on the implementation and platform but this time we favor thread_ref
-        slightly. Given all of this it&#39;s a narrow margin, but the thread
-        design prevails.</p>
-
-        <p>Given this analysis, and the fact that noncopyable objects for
-        system resources are the normal designs that C++ programmers are used
-        to dealing with, the Boost.Threads library has gone with a noncopyable
-        design.</p>
-
-        <h2>Rationale for not providing <i><a name="Events">Event</a>
-        Variables</i></h2>
-
-        <p><i>Event variables</i> are simply far too error-prone. <a href=
-        "condition.html">Condition variables</a> are a much safer
-        alternative.</p>
-
-        <p>[Note that Graphical User Interface <i>events</i> are a different
-        concept, and are not what is being discussed here.]</p>
-
-        <p>Event variables were one of the first synchronization primitives.
-        They are still used today, for example, in the native Windows
-        multithreading API.</p>
-
-        <p>Yet both respected computer science researchers and experienced
-        multithreading practitioners believe event variables are so inherently
-        error-prone that they should never be used, and thus should not be part
-        of a multithreading library.</p>
-
-        <p>Per Brinch Hansen <a href="bibliography.html#Brinch-Hansen-73">
-        [Brinch Hansen 73]</a> analyzed event variables in some detail,
-        pointing out [emphasis his] that &quot;<i>event operations force the
-        programmer to be aware of the relative speeds of the sending and
-        receiving processes</i>&quot;. His summary:</p>
-
-        <blockquote>
-            <p>We must therefore conclude that event variables of the previous
-            type are impractical for system design. <i>The effect of an
-            interaction between two processes must be independent of the speed
-            at which it is carried out.</i></p>
-        </blockquote>
-
-        <p>Experienced programmers using the Windows platform today report that
-        event variables are a continuing source of errors, even after previous
-        bad experiences caused them to be very careful in their use of event
-        variables. Overt problems can be avoided, for example, by teaming the
-        event variable with a mutex, but that may just convert a <a href=
-        "definitions.html#Race condition">race condition</a> into another
-        problem, such as excessive resource use. One of the most distressing
-        aspects of the experience reports is the claim that many defects are
-        latent. That is, the programs appear to work correctly, but contain
-        hidden timing dependencies which will cause them to fail when
-        environmental factors or usage patterns change, altering relative
-        thread timings.</p>
-
-        <p>The decision to exclude event variables from Boost.Threads has been
-        surprising to some Windows programmers. They have written programs
-        which work using event variables, and wonder what the problem is. It
-        seems similar to the &quot;goto considered harmful&quot; controversy of
-        30 years ago. It isn&#39;t that events, like gotos, can&#39;t be made
-        to work, but rather that virtually all programs using alternatives will
-        be easier to write, debug, read, maintain, and be less likely to
-        contain latent defects.</p>

-
-        <p>The <code>recursive_mutex</code>, <code>recursive_try_mutex</code>
-        and <code>recursive_timed_mutex</code> classes define full featured
-        models of the <a href="mutex_concept.html#Mutex">Mutex</a>, <a href=
-        "mutex_concept.html#TryMutex">TryMutex</a> and <a href=
-        "mutex_concept.html#TimedMutex">TimedMutex</a> concepts with recursive
-        locking semantics. These types should be used to synchronize access to
-        shared resources when recursive locking by a single thread is likely to
-        occur. A good example for this is when a class supplies &quot;internal
-        synchronization&quot; to ensure <a href="definitions.html#Thread-safe">
-        thread-safety</a> and a function of the class may have to call other
-        functions of the class which also attempt to lock the mutex. For
-        recursive locking mechanics, see <a href="mutex.html">mutexes</a>.</p>
-
-        <p>Each class supplies one or more typedefs for lock types which model
-        matching lock concepts. For the best possible performance you should
-        use the mutex class that supports the minimum set of lock types that
-        you need.</p>

-
-        <p>This class template defines a generic lock type which meets the <a
-        href="lock_concept.html#ScopedLock">ScopedLock</a> requirements. The <a
-        href="mutex.html">mutex</a>, <a href="mutex.html">try_mutex</a>, <a
-        href="mutex.html">timed_mutex</a>, <a href="recursive_mutex.html">

-        recursive_try_mutex</a> and <a href="recursive_mutex.html">
-        recursive_timed_mutex</a> classes all use this template to define their
-        <code>scoped_lock</code> types.</p>
-
-        <p>Like all the <b>Boost.Threads</b> <a href="lock_concept.html">lock
-        models</a>, <code>scoped_lock</code> objects are meant to be
-        short-lived. Objects of the class are not <a href=
-        "definitions.html#thread-safe">thread-safe</a>, and so should not be
-        shared between threads.</p>
-
-        <p>Class <code>scoped_lock</code> follows the &quot;resource
-        acquisition is initialization&quot; idiom <a href=
-        "bibliography.html#Stroustrup-00">[Stroustrup 00 14.4.1]</a> and is a
-        realization of the &quot;Scoped Locking Pattern&quot; <a href=
-        "bibliography.html#Schmidt-00">[Schmidt-00]</a>. Thus the usage is to
-        let the constructor do the locking, and then let the destructor do the
-        unlocking automatically at the end of the enclosing scope. The lock()
-        and unlock() members are usually not explicitly called, but are
-        provided to allow for complex overlapping locks of multiple
-        mutexes.</p>
-
-        <p>The type used to instantiate the class must meet the <a href=
-        "mutex_concept.html#Mutex">Mutex</a> requirements.</p>
-
-        <p>Although this class is an implementation detail, it is publicly
-        documented here because of its importance.</p>

+[section:motovation Motivation]
+Based on the scoped_thread class defined in C++ Concurrency in Action Boost.Thread defines a thread wrapper class that instead of calling terminate if the thread is joinable on destruction, call a specific action given as template parameter.
+
+While the scoped_thread class defined in C++ Concurrency in Action is closer to strict_scoped_thread class that doesn't allows any change in the wrapped thread, Boost.Thread provides a class scoped_thread that provides the same non-deprecated interface than __thread.
+
+[endsect]
+
+[section:tutorial Tutorial]
+
+Scoped Threads are wrappers around a thread that allows the user to state what to do at destruction time. One of the common uses is to join the thread at destruction time so this is the default behavior. This is the single difference respect to a thread. While thread call std::terminate() on the destructor is the thread is joinable, strict_scoped_thread<> or scoped_thread<> join the thread if joinable.
+
+The difference between strict_scoped_thread and scoped_thread is that the strict_scoped_thread hides completely the owned thread and so the user can do nothing with the owned thread other than the specific action given as parameter, while scoped_thread provide the same interface than __thread and forwards all the operations.

-        <h2><a name="Introduction">Introduction</a></h2>
-
-        <p>This class template defines a generic lock type which meets the <a
-        href="lock_concept.html#ScopedTimedLock">ScopedTimedLock</a>
-        requirements. The <a href="mutex.html">timed_mutex</a> and <a href=
-        "recursive_mutex.html">recursive_timed_mutex</a> classes use this
-        template to define their <code>scoped_timed_lock</code> types.</p>
-
-        <p>Like all the <b>Boost.Threads</b> <a href="lock_concept.html">lock
-        models</a>, <code>scoped_timed_lock</code> objects are meant to be
-        short-lived. Objects of the class are not <a href=
-        "definitions.html#thread-safe">thread-safe</a>, and so should not be
-        shared between threads.</p>
-
-        <p>Class <code>scoped_timed_lock</code> follows the &quot;resource
-        acquisition is initialization&quot; idiom <a href=
-        "bibliography.html#Stroustrup-00">[Stroustrup 00 14.4.1]</a> and is a
-        realization of the &quot;Scoped Locking Pattern&quot; <a href=
-        "bibliography.html#Schmidt-00">[Schmidt-00]</a>. Thus the usage is to
-        let the constructor do the locking, and then let the destructor do the
-        unlocking automatically at the end of the enclosing scope. The lock()
-        and unlock() members are usually not explicitly called, but are
-        provided to allow for complex overlapping locks of multiple
-        mutexes.</p>
-
-        <p>The type used to instantiate the class must meet the <a href=
-        "mutex_concept.html#TimedMutex">TimedMutex</a> requirements.</p>
-
-        <p>Although this class is an implementation detail, it is publicly
-        documented here because of its importance.</p>

-        <h2><a name="Introduction">Introduction</a></h2>
-
-        <p>This class template defines a generic lock type which meets the <a
-        href="lock_concept.html#ScopedTryLock">ScopedTryLock</a> requirements.
-        The <a href="mutex.html">try_mutex</a>, <a href="mutex.html">
-        timed_mutex</a>, <a href="recursive_mutex.html">recursive_try_mutex</a>
-        and <a href="recursive_mutex.html">recursive_timed_mutex</a> classes
-        use this template to define their <code>scoped_try_lock</code>
-        types.</p>
-
-        <p>Like all the <b>Boost.Threads</b> <a href="lock_concept.html">lock
-        models</a>, <code>scoped_try_lock</code> objects are meant to be
-        short-lived. Objects of the class are not <a href=
-        "definitions.html#thread-safe">thread-safe</a>, and so should not be
-        shared between threads.</p>
-
-        <p>Class <code>scoped_try_lock</code> follows the &quot;resource
-        acquisition is initialization&quot; idiom <a href=
-        "bibliography.html#Stroustrup-00">[Stroustrup 00 14.4.1]</a> and is a
-        realization of the &quot;Scoped Locking Pattern&quot; <a href=
-        "bibliography.html#Schmidt-00">[Schmidt-00]</a>. Thus the usage is to
-        let the constructor do the locking, and then let the destructor do the
-        unlocking automatically at the end of the enclosing scope. The lock()
-        and unlock() members are usually not explicitly called, but are
-        provided to allow for complex overlapping locks of multiple
-        mutexes.</p>
-
-        <p>Although this class is an implementation detail, it is publicly
-        documented here because of its importance.</p>
-
-        <p>The type used to instantiate the class must meet the <a href=
-        "mutex_concept.html#TryMutex">TryMutex</a> requirements.</p>

+
+Note the the lack of reader-writer priority policies in shared_mutex. This is due to an algorithm credited to Alexander Terekhov which lets the OS decide which thread is the next to get the lock without caring whether a unique lock or shared lock is being sought. This results in a complete lack of reader or writer starvation. It is simply fair.

-        <h2><a name="Introduction">Introduction</a></h2>
-
-        <p>The <code>thread</code> class represents threads of execution, and
-        provides the functionality to create and manage threads within the <b>
-        Boost.Threads</b> library. See <a href="definitions.html">
-        Definitions</a> for a precise description of &quot;thread of
-        execution&quot;, and for definitions of threading related terms and of
-        thread states such as &quot;blocked&quot;.</p>
-
-        <p>A thread of execution has an initial function. For the program&#39;s
-        initial thread, the initial function is <code>main()</code>. For other
-        threads, the initial function is <code>operator()</code> of the
-        function object passed to the class <code>thread</code>
-        constructor.</p>
-
-        <p>A thread of execution is said to be &quot;finished&quot; or
-        &quot;finished execution&quot; when its initial function returns or is
-        terminated. This includes completion of all thread cleanup handlers,
-        and completion of the normal C++ function return behaviors, such as
-        destruction of automatic storage (stack) objects and releasing any
-        associated implementation resources.</p>
-
-        <p>A thread object has an associated state which is either
-        &quot;joinable&quot; or &quot;non-joinable&quot;.</p>
-
-        <p>Except as described below, the policy used by an implementation of
-        <b>Boost.Threads</b> to schedule transitions between thread states is
-        unspecified.</p>
-
-        <p><b>Note:</b> Just as the lifetime of a file may be different from
-        the lifetime of an iostream object which represents the file, the
-        lifetime of a thread of execution may be different from the <code>
-        thread</code> object which represents the thread of execution. In
-        particular, after a call to <code>join()</code>, the thread of
-        execution will no longer exist even though the <code>thread</code>
-        object continues to exist until the end of its normal lifetime. The
-        converse is also possible; if a <code>thread</code> object is destroyed
-        without <code>join()</code> having first been called, the thread of
-        execution continues until its initial function completes.</p>

-        <p><b>Effects:</b> Starts a new thread of execution and constructs a

-        threadfunc</code> (which in turn copies the function object wrapped by
-        <code>threadfunc</code>) to an internal location which persists for the
-        lifetime of the new thread of execution. Calls <code>operator()</code>
-        on the copy of the <code>threadfunc</code> function object in the new

-        has been destroyed.</p>
-
-        <p><b>Notes:</b> If <code>*this</code> is joinable the actual thread of
-        execution becomes &quot;detached&quot;. Any resources used by the
-        thread will be reclaimed when the thread of execution completes. To
-        ensure such a thread of execution runs to completion before the <code>
-        thread</code> object is destroyed, call <code>join()</code>.</p>

-<pre>
-    bool operator==(const thread&amp; rhs);
-</pre>
-
-        <p><b>Requires:</b> The thread is non-terminated or <code>*this</code>
-        is joinable.</p>
-
-        <p><b>Returns:</b> <code>true</code> if <code>*this</code> and <code>

-        *this</code> finishes and all resources are reclaimed.</p>
-
-        <p><b>Postcondition:</b> <code>*this</code> is non-joinable.</p>
-
-        <p><b>Note:</b> If <code>*this == thread()</code> the result is

-<pre>
-    static void sleep(const <a href="xtime.html">xtime</a>&amp; xt);

-
-        <p><b>Effects:</b> The current thread of execution is placed in the
-        &quot;ready&quot; state.</p>

-        <p><b>Notes:</b> Allow the current thread to give up the rest of its
-        time slice (or other scheduling quota) to another thread. Particularly
-        useful in non-preemptive implementations.</p>

-        <p>The <code>thread_specific_ptr</code> class defines an interface for

+[section:time Time Requirements]
+
+As of Boost 1.50.0, the __boost_thread__ library uses Boost.Chrono library for all operations that require a
+time out as defined in the standard c++11. These include (but are not limited to):
+
+* `boost::this_thread::__sleep_for`
+* `boost::this_thread::__sleep_until`
+* `boost::__thread::__try_join_for`
+* `boost::__thread::__try_join_until`
+* `boost::__condition_variable::__wait_for`
+* `boost::__condition_variable::__wait_until`
+* `boost::__condition_variable_any::__cvany_wait_for`
+* `boost::__condition_variable_any::__cvany_wait_until`
+* `__TimedLockable::__try_lock_for`
+* `__TimedLockable::__try_lock_until`
+
+[section:deprecated Deprecated]
+The time related functions introduced in Boost 1.35.0, using the [link date_time Boost.Date_Time] library are deprecated. These include (but are not limited to):
+
+* __sleep__
+* __timed_join__
+* __cond_timed_wait__
+* __timed_lock_ref__
+
+For the overloads that accept an absolute time parameter, an object of type [link thread.time.deprecated.system_time `boost::system_time`] is
+required. Typically, this will be obtained by adding a duration to the current time, obtained with a call to [link
+thread.time.deprecated.get_system_time `boost::get_system_time()`]. e.g.
+
+    boost::system_time const timeout=boost::get_system_time() + boost::posix_time::milliseconds(500);

+
+For the overloads that accept a ['TimeDuration] parameter, an object of any type that meets the [link
+date_time.posix_time.time_duration Boost.Date_Time Time Duration requirements] can be used, e.g.
+
+    boost::this_thread::sleep(boost::posix_time::milliseconds(25));

+[section Thread Local Storage]
+
+[heading Synopsis]
+
+Thread local storage allows multi-threaded applications to have a separate instance of a given data item for each thread. Where a
+single-threaded application would use static or global data, this could lead to contention, deadlock or data corruption in a
+multi-threaded application. One example is the C `errno` variable, used for storing the error code related to functions from the
+Standard C library. It is common practice (and required by POSIX) for compilers that support multi-threaded applications to provide
+a separate instance of `errno` for each thread, in order to avoid different threads competing to read or update the value.
+
+Though compilers often provide this facility in the form of extensions to the declaration syntax (such as `__declspec(thread)` or
+`__thread` annotations on `static` or namespace-scope variable declarations), such support is non-portable, and is often limited in
+some way, such as only supporting POD types.
+
+[heading Portable thread-local storage with `boost::thread_specific_ptr`]
+
+`boost::thread_specific_ptr` provides a portable mechanism for thread-local storage that works on all compilers supported by
+__boost_thread__. Each instance of `boost::thread_specific_ptr` represents a pointer to an object (such as `errno`) where each
+thread must have a distinct value. The value for the current thread can be obtained using the `get()` member function, or by using
+the `*` and `->` pointer deference operators. Initially the pointer has a value of `NULL` in each thread, but the value for the
+current thread can be set using the `reset()` member function.
+
+If the value of the pointer for the current thread is changed using `reset()`, then the previous value is destroyed by calling the
+cleanup routine. Alternatively, the stored value can be reset to `NULL` and the prior value returned by calling the `release()`
+member function, allowing the application to take back responsibility for destroying the object.
+
+[heading Cleanup at thread exit]
+
+When a thread exits, the objects associated with each `boost::thread_specific_ptr` instance are destroyed. By default, the object
+pointed to by a pointer `p` is destroyed by invoking `delete p`, but this can be overridden for a specific instance of
+`boost::thread_specific_ptr` by providing a cleanup routine to the constructor. In this case, the object is destroyed by invoking
+`func(p)` where `func` is the cleanup routine supplied to the constructor. The cleanup functions are called in an unspecified
+order. If a cleanup routine sets the value of associated with an instance of `boost::thread_specific_ptr` that has already been
+cleaned up, that value is added to the cleanup list. Cleanup finishes when there are no outstanding instances of
+`boost::thread_specific_ptr` with values.
+
+Note: on some platforms, cleanup of thread-specific data is not
+performed for threads created with the platform's native API. On those
+platforms such cleanup is only done for threads that are started with
+`boost::thread` unless `boost::on_thread_exit()` is called manually
+from that thread.
+
+[heading Rationale about the nature of the key]
+
+Boost.Thread uses the address of the `thread_specific_ptr` instance as key of the thread specific pointers. This avoids to create/destroy a key which will need a lock to protect from race conditions. This has a little performance liability, as the access must be done using an associative container.

-        <p>The <code>xtime</code> type is used to represent a point on some
-        time scale or a duration in time. This type may be proposed for the C
-        standard by Markus Kuhn. <b>Boost.Threads</b> provides only a very
-        minimal implementation of this proposal and it&#39;s expected that a
-        full implementation will be provided in Boost as a separate library, at
-        which time <b>Boost.Threads</b> will deprecate its implementation.</p>

-
-        <p><b>Notes:</b> The resolution is implementation specific. For many
-        implementations the best resolution of time is far more than one
-        nanosecond, and even when the resolution is reasonably good, the
