+# 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
+directories was devised by Roland, and his input has contributed greatly to improving the quality of the current implementation.
+
+Thanks also must go to Peter Dimov, Howard Hinnant, Alexander Terekhov, Chris Thomasson and others for their comments on the
+implementation details of the code.

+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:changes 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.

-<h2><a name="Introduction">Introduction</a></h2>
-
-<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'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'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'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 "waiting" is a synonym
-for blocked.</p>

+[section:condvar_ref Condition Variables]
+
+[heading Synopsis]
+
+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`.

-<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].&nbsp; 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.&nbsp; For example, files.</li>
-</ul>
-<ul>
-  <li>The program itself.&nbsp; 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>
-</ul>
-<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>
-<h3>Thread <a name="State">State</a></h3>
-<p>During the lifetime of a thread, it shall be in one of the following
-states:</p>
-<table border="1" cellpadding="5">
-  <tr>
-    <td><b>State</b></td>
-    <td><b>Description</b></td>
-  </tr>
-  <tr>
-    <td>Ready</td>
-    <td>Ready to run, but waiting for a processor.</td>
-  </tr>
-  <tr>
-    <td>Running</td>
-    <td>Currently executing on a processor. Zero or more threads may be running
-      at any time, with a maximum equal to the number of processors.&nbsp;</td>
-  </tr>
-  <tr>
-    <td>Blocked</td>
-    <td>Waiting for some resource other than a processor which is not currently
-      available, or for the completion of calls to library functions [1.9/6].
-      The term &quot;waiting&quot; is synonymous for &quot;blocked&quot;</td>
-  </tr>
-  <tr>
-    <td>Terminated</td>
-    <td>Finished execution but not yet detached or joined.</td>
-  </tr>
-</table>
-<p>Thread state transitions shall occur only as specified:</p>
-<table border="1" cellpadding="5">
-  <tr>
-    <td><b>From</b></td>
-    <td><b>To</b></td>
-    <td><b>Cause</b></td>
-  </tr>
-  <tr>
-    <td>
-      <p align="left">[none]</td>
-    <td>Ready</td>
-    <td>Thread is created by a call to a library function.&nbsp; In the case of
-      the initial thread, creation is implicit and occurs during the startup of
-      the main() function [3.6.1].</td>
-  </tr>
-  <tr>
-    <td>Ready</td>
-    <td>Running</td>
-    <td>Processor becomes available.</td>

-  <tr>
-    <td>Running</td>
-    <td>Ready</td>
-    <td>Thread preempted.</td>
-  </tr>
-  <tr>
-    <td>Running</td>
-    <td>Blocked</td>
-    <td>Thread calls a library function which waits for a resource or for the
-      completion of I/O.</td>
-  </tr>
-  <tr>
-    <td>Running</td>
-    <td>Terminated</td>
-    <td>Thread returns from its initial function, calls a thread termination
-      library function, or is cancelled by some other thread calling a thread
-      termination library function.</td>
-  </tr>
-  <tr>
-    <td>Blocked</td>
-    <td>Ready</td>
-    <td>The resource being waited for becomes available, or the blocking library
-      function completes.</td>
-  </tr>
-  <tr>
-    <td>Terminated</td>
-    <td>[none]</td>
-    <td>Thread is detached or joined by some other thread calling the
-      appropriate library function, or by program termination [3.6.3].</td>
-  </tr>
-</table>
-<p>[Note: if a suspend() function is added to the threading library, additional
-transitions to the blocked state will have to be added to the above table.]</p>
-<h3><a name="Race condition">Race condition</a></h3>
-<p>A race condition is what occurs when multiple threads read and
-write to the same memory without proper synchronization, resulting in an
-incorrect value being read or written.&nbsp; The result of a race condition may
-be a bit pattern which isn't even a valid value for the data type. A race
-condition results in undefined behavior [1.3.12].</p>
-<p>Race conditions can be prevented by serializing memory access
-using the tools provided by Boost.Threads.&nbsp;</p>
-<h3><a name="Deadlock">Deadlock</a></h3>
-<p>Deadlock is an execution state where for some set of threads, each thread in
-the set is blocked waiting for some action by one of the other threads in the
-set. Since each is waiting on the others, none will ever become ready again.</p>
-<h3><a name="Priority failure">Priority failure</a></h3>
-<p>A priority failure (such as priority inversion or infinite overtaking) occurs
-when threads executed in such a sequence that required work is not performed in
-time to be useful.</p>
-<h2>Memory visibility between threads</h2>
-<p>An address [1.7] shall always point to the same memory byte, regardless of the
-thread or processor dereferencing the address.</p>
-<p>An object [1.8, 1.9] is accessible from multiple threads if it is of
-static storage duration (static, extern) [3.7.1], or if a pointer or reference to
-it is explicitly or
-implicitly dereferenced in multiple threads.</p>
-<p>For an object accessible from multiple threads, the value of the object
-accessed from one thread may be indeterminate or different than the value
-accessed from another thread, except under the conditions specified in the following
-table.&nbsp;&nbsp; For the same row of the table, the value of an object
-accessible at the indicated sequence point in thread A will be determinate and the
-same if accessed at or after the indicated sequence point in thread B, provided
-the object is not otherwise modified. In the table, the
-&quot;sequence point at a call&quot; is the sequence point after the evaluation
-of all function arguments [1.9/17], while the &quot;sequence point after a
-call&quot; is the sequence point after the copying of the returned
-value...&quot; [1.9/17].</p>
-<table border="1" cellpadding="5">
-  <tr>
-    <td align="center"><b>Thread A</b></td>

-  </tr>
-  <tr>
-    <td>The sequence point at a call to a library thread-creation

-<p>The architecture of the execution environment and the observable behavior of
-the abstract machine [1.9] shall be the same on all processors.</p>
-<p>The latitude granted by the C++ standard for an implementation to alter the
-definition of observable behavior of the abstract machine to include additional library I/O
-functions [1.9/6] is extended to include threading library functions.</p>
-<p>When an exception is thrown and there is no matching exception handler in the
-same thread, behavior is undefined.&nbsp; The preferred behavior is the same as when there is no matching exception handler
-in a program [15.3/9].&nbsp; That is, terminate() is called, and it is implementation defined
-whether or not the stack is unwound.</p>

-<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'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'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't model such C based
-APIs.</p>
-
-<h2>2b. Why wasn'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't meet
-our C++ requirements, and were also missing certain features. For
-instance, POSIX threads doesn't support a maximum value for semaphores.
-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'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'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'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'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'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);
-      return m_value;
-   }
-   int increment()
-   {
-      boost::mutex::scoped_lock scoped_lock(m_mutex);
-      return ++m_value;
-   }
-   
-private:
-   mutable boost::mutex m_mutex;
-   int m_value;
-};
-</pre>
-
-<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't thread cancellation or termination provided?</h2>
-
-<p>There'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>

-<h3>Motivation</h3>
-
-<p>With client/server and three-tier architectures becoming common place in today's
-world, it'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++'s strengths, or to address C++'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><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

-<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 "state of the art" and the only concepts available to programmers.  Recently
-there has been a lot of research in other concepts, such as in "Communicating Sequential
-Processes."  <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's a big problem faced by developers wishing to supply such high quality
-libraries, namely thread-safety.  The C++ standard doesn't address threads at all, but real
-world programs often make use of native threading support.  A portable library that doesn'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's a very great need for portable
-primitives that will allow the library developer to create <a href="file:///c:/boost/site/libs/thread/doc/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="semaphore.html">semaphore</a>, <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 "core" 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'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>

-<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'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'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'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's locked it before the mutex model'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'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>Concept <a name="Requirements">Requirements</a></h2>

+[section:mutex_concepts Mutex Concepts]
+
+A mutex object facilitates protection against data races and allows thread-safe synchronization of data between threads. A thread
+obtains ownership of a mutex object by calling one of the lock functions and relinquishes ownership by calling the corresponding
+unlock function. Mutexes may be either recursive or non-recursive, and may grant simultaneous ownership to one or many
+threads. __boost_thread__ supplies recursive and non-recursive mutexes with exclusive ownership semantics, along with a shared
+ownership (multiple-reader / single-writer) mutex.
+
+__boost_thread__ supports four basic concepts for lockable objects: __lockable_concept_type__, __timed_lockable_concept_type__,
+__shared_lockable_concept_type__ and __upgrade_lockable_concept_type__. Each mutex type implements one or more of these concepts, as
+do the various lock types.
+
+[section:lockable `Lockable` Concept]
+
+The __lockable_concept__ models exclusive ownership. A type that implements the __lockable_concept__ shall provide the following
+member functions:
+
+* [lock_ref_link `void lock();`]
+* [try_lock_ref_link `bool try_lock();`]
+* [unlock_ref_link `void unlock();`]
+
+Lock ownership acquired through a call to __lock_ref__ or __try_lock_ref__ must be released through a call to __unlock_ref__.
+

+
+[section:timed_lockable `TimedLockable` Concept]
+
+The __timed_lockable_concept__ refines the __lockable_concept__ to add support for
+timeouts when trying to acquire the lock.
+
+A type that implements the __timed_lockable_concept__ shall meet the requirements
+of the __lockable_concept__. In addition, the following member functions must be
+provided:
+
+* [timed_lock_ref_link `bool timed_lock(boost::system_time const& abs_time);`]
+* [timed_lock_duration_ref_link `template<typename DurationType> bool timed_lock(DurationType const& rel_time);`]
+

+
+[section:shared_lockable `SharedLockable` Concept]
+
+The __shared_lockable_concept__ is a refinement of the __timed_lockable_concept__ that
+allows for ['shared ownership] as well as ['exclusive ownership]. This is the
+standard multiple-reader / single-write model: at most one thread can have
+exclusive ownership, and if any thread does have exclusive ownership, no other threads
+can have shared or exclusive ownership. Alternatively, many threads may have
+shared ownership.
+
+For a type to implement the __shared_lockable_concept__, as well as meeting the
+requirements of the __timed_lockable_concept__, it must also provide the following
+member functions:
+
+* [lock_shared_ref_link `void lock_shared();`]
+* [try_lock_shared_ref_link `bool try_lock_shared();`]
+* [unlock_shared_ref_link `bool unlock_shared();`]

+
+Lock ownership acquired through a call to __lock_shared_ref__, __try_lock_shared_ref__ or __timed_lock_shared_ref__ must be released
+through a call to __unlock_shared_ref__.

+[section:upgrade_lockable `UpgradeLockable` Concept]
+
+The __upgrade_lockable_concept__ is a refinement of the __shared_lockable_concept__ that allows for ['upgradable ownership] as well
+as ['shared ownership] and ['exclusive ownership]. This is an extension to the multiple-reader / single-write model provided by the
+__shared_lockable_concept__: a single thread may have ['upgradable ownership] at the same time as others have ['shared
+ownership]. The thread with ['upgradable ownership] may at any time attempt to upgrade that ownership to ['exclusive ownership]. If
+no other threads have shared ownership, the upgrade is completed immediately, and the thread now has ['exclusive ownership], which
+must be relinquished by a call to __unlock_ref__, just as if it had been acquired by a call to __lock_ref__.
+
+If a thread with ['upgradable ownership] tries to upgrade whilst other threads have ['shared ownership], the attempt will fail and
+the thread will block until ['exclusive ownership] can be acquired.
+
+Ownership can also be ['downgraded] as well as ['upgraded]: exclusive ownership of an implementation of the
+__upgrade_lockable_concept__ can be downgraded to upgradable ownership or shared ownership, and upgradable ownership can be
+downgraded to plain shared ownership.
+
+For a type to implement the __upgrade_lockable_concept__, as well as meeting the
+requirements of the __shared_lockable_concept__, it must also provide the following
+member functions:
+
+* [lock_upgrade_ref_link `void lock_upgrade();`]
+* [unlock_upgrade_ref_link `bool unlock_upgrade();`]
+* [unlock_upgrade_and_lock_ref_link `void unlock_upgrade_and_lock();`]
+* [unlock_and_lock_upgrade_ref_link `void unlock_and_lock_upgrade();`]
+* [unlock_upgrade_and_lock_shared_ref_link `void unlock_upgrade_and_lock_shared();`]
+
+Lock ownership acquired through a call to __lock_upgrade_ref__ must be released through a call to __unlock_upgrade_ref__. If the
+ownership type is changed through a call to one of the `unlock_xxx_and_lock_yyy()` functions, ownership must be released through a
+call to the unlock function corresponding to the new level of ownership.

+
+__unique_lock__ is more complex than __lock_guard__: not only does it provide for RAII-style locking, it also allows for deferring
+acquiring the lock until the __lock_ref__ member function is called explicitly, or trying to acquire the lock in a non-blocking
+fashion, or with a timeout. Consequently, __unlock_ref__ is only called in the destructor if the lock object has locked the
+__lockable_concept_type__ object, or otherwise adopted a lock on the __lockable_concept_type__ object.
+
+Specializations of __unique_lock__ model the __timed_lockable_concept__ if the supplied __lockable_concept_type__ type itself models
+__timed_lockable_concept__ (e.g. `boost::unique_lock<boost::timed_mutex>`), or the __lockable_concept__ otherwise
+(e.g. `boost::unique_lock<boost::mutex>`). 
+
+An instance of __unique_lock__ is said to ['own] the lock state of a __lockable_concept_type__ `m` if __mutex_func_ref__ returns a
+pointer to `m` and __owns_lock_ref__ returns `true`. If an object that ['owns] the lock state of a __lockable_concept_type__ object
+is destroyed, then the destructor will invoke [unlock_ref_link `mutex()->unlock()`].
+
+The member functions of __unique_lock__ are not thread-safe. In particular, __unique_lock__ is intended to model the ownership of a
+__lockable_concept_type__ object by a particular thread, and the member functions that release ownership of the lock state
+(including the destructor) must be called by the same thread that acquired ownership of the lock state.

+
+Like __unique_lock__, __upgrade_lock__ models the __lockable_concept__, but rather than acquiring unique ownership of the supplied
+__lockable_concept_type__ object, locking an instance of __upgrade_lock__ acquires upgrade ownership.
+
+Like __unique_lock__, not only does it provide for RAII-style locking, it also allows for deferring acquiring the lock until the
+__lock_ref__ member function is called explicitly, or trying to acquire the lock in a non-blocking fashion, or with a
+timeout. Consequently, __unlock_ref__ is only called in the destructor if the lock object has locked the __lockable_concept_type__
+object, or otherwise adopted a lock on the __lockable_concept_type__ object.
+
+An instance of __upgrade_lock__ is said to ['own] the lock state of a __lockable_concept_type__ `m` if __mutex_func_ref__ returns a
+pointer to `m` and __owns_lock_ref__ returns `true`. If an object that ['owns] the lock state of a __lockable_concept_type__ object
+is destroyed, then the destructor will invoke [unlock_upgrade_ref_link `mutex()->unlock_upgrade()`].
+
+The member functions of __upgrade_lock__ are not thread-safe. In particular, __upgrade_lock__ is intended to model the upgrade
+ownership of a __lockable_concept_type__ object by a particular thread, and the member functions that release ownership of the lock
+state (including the destructor) must be called by the same thread that acquired ownership of the lock state.

+
+__upgrade_to_unique_lock__ allows for a temporary upgrade of an __upgrade_lock__ to exclusive ownership. When constructed with a
+reference to an instance of __upgrade_lock__, if that instance has upgrade ownership on some __lockable_concept_type__ object, that
+ownership is upgraded to exclusive ownership. When the __upgrade_to_unique_lock__ instance is destroyed, the ownership of the
+__lockable_concept_type__ is downgraded back to ['upgrade ownership].

-<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 call 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.&nbsp; 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.&nbsp;
-    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!&nbsp;</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><a href="definitions.html#Deadlock">Deadlock</a> (sometimes called
-    &quot;deadly embrace&quot;)
-  <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.&nbsp; These aren't rare or exotic failures - they are
-virtually guaranteed to occur unless multi-threaded code is designed to avoid
-them.&nbsp; 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.&nbsp; That can make testing and debugging a nightmare:</p>
-<ul>
-  <li>Failures are often not repeatable.
-  <li>Probe effect causes debuggers to produce very different results from
-    non-debug uses.
-  <li>Debuggers require special support to show thread state.
-  <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.&nbsp;</li>
-  <li>For programs which create a varying number of threads according to
-    workload, tests which don'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>].&nbsp; 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>Reading and study first yields a head start toward designing 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.&nbsp;&nbsp;</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&nbsp;</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.&nbsp; 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.&nbsp;
-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.&nbsp; 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>

-<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 "potential parallelism" 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't directly support this concept.</p>
-
-<p>Many platforms support multi-threaded programming despite the fact that the language doesn'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 "pthread" 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's available in a C library.</p>
-
-<p>What'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's a hope that the library can
-be the basis for a more detailed proposal for the C++ standards committee to consider for inclusion

-<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 semaphores, 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's no way to mathematically prove that a
-usage pattern is correct, meaning it doesn'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'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's also an argument for accessibility.</p>
-
-<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's design for mutex lock concepts is not <a href="file:///c:/boost/site/libs/thread/doc/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's not thread-safe itself?</p>
-
-<p>A lock object is not a synchronization primitive.  A lock object's sole responsibility is
-to ensure that a mutex is both locked and unlocked in a manner that won'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't
-be shared between threads.  Only the mutex objects will be created outside of block scope and/or
-shared between threads.  Though it'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'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't a problem, and so long
-as the lock object is properly used there'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'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'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'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 "reference management" were used, such as ref-counting
-or ref-lists, and many argued for a boost::thread_ref design instead.  The reasoning was
-that copying "thread" 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't appear to
-bear them out.  To illustrate the analysis we'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'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's only one that requires reference management (number 6).
-Hopefully it's fairly obvious that this usage pattern simply won't occur as often as the
-other usage patterns.  So there really isn't a "typical need" for a thread concept, though
-there is some need.</p>
-
-<p>Since the need isn'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'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'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'll code all six usage
-patterns using both designs.</p>
-
-<h3>1.</h3>
-
-<pre>
-void foo()
-{
-   thread thrd(&amp;bar);
-}
-
-void foo()
-{
-   thread_ref thrd = create_thread(&amp;bar);
-}
-</pre>
-

-   thread_ref thrd = 
-   create_thread(&amp;bar);thrd-&gt;join();
-}
-</pre>
-
-<h3>3.</h3>
-
-<pre>
-void foo()
-{
-   for (int i=0; i&lt;NUM_THREADS; ++i)
-      thread thrd(&amp;bar);
-}
-
-void foo()
-{
-   for (int i=0; i&lt;NUM_THREADS; ++i)

-      threads[i] = std::auto_ptr&lt;thread&gt;(new thread(&amp;bar));
-   for (int i= 0; i&lt;NUM_THREADS;
-      ++i)threads[i]-&gt;join();
-}
-
-void foo()
-{
-   thread_ref threads[NUM_THREADS];
-   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]-&gt;join();    
-}
-</pre>
-
-<h3>5.</h3>
-
-<pre>
-void foo()
-{
-   thread thrd* = new thread(&amp;bar);
-   manager.owns(thread);
-}
-
-void foo()
-{
-   thread_ref thrd = create_thread(&amp;bar);
-   manager.owns(thrd);
-}
-</pre>
-
-<h3>6.</h3>
-
-<pre>
-void foo()
-{
-   boost::shared_ptr&lt;thread&gt; thrd(new thread(&amp;bar));
-   manager1.add(thrd);
-   manager2.add(thrd);
-}
-
-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'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'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'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'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.&nbsp; <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.&nbsp; 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.&nbsp; 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.&nbsp; They have written programs which
-work using event variables, and wonder what the problem is.&nbsp; It seems
-similar to the &quot;goto considered harmful&quot; controversy of 30 years ago.
-It isn't that events, like gotos, can'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>

-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

-
-<p>Class <code> scoped_lock</code> follows the &quot;resource acquisition is

-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>

-<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>

-<h2><a name="Introduction">Introduction</a></h2>
-
-<p>The <tt>semaphore</tt> class defines a classic synchronization primitive invented by the
-Dutch computer scientist Edsger W. Dijkstra.  A semaphore manages an internal counter.  This
-counter never goes below zero, or above a specified maximum value.  When calling
-<tt>semaphore::down</tt> the calling thread will block until the value is non-zero and then
-decrement the value in a single atomic operation.  When calling <tt>semaphore::up</tt> the
-calling thread will increment the value in a single atomic operation, failing if the value has
-already reached the specified maximum.</p>
-
-<p><b>Rationale:</b> The semaphore is the simplest synchronization primitive available and is generally the
-primitive used to build other synchronization concepts at some level of implementation. For this
-reason <b>Boost.Threads</b> defines the <tt>semaphore</tt> type in the classic form.  This simplifies
-usage and implementation, but it means that the interface is not as safe as other <b>Boost.Threads</b>
-interfaces.</p>
-
-<p><b><a name="Danger">Danger</a>:</b> Unlike the <A href="mutex_concept.html">mutex models</a> supplied by <b>Boost.Threads,</b>
-there is no <A href="lock_concept.html">lock_concept</a> for the semaphore to help ensure proper
-usage. Great care must be taken when using a <tt>semaphore</tt> object to ensure
-<a href="definitions.html#Deadlock"> deadlock</a> or <a href="definitions.html#Race condition">race conditions</a> do not occur.&nbsp;</p>
-
-<p>The dangers are spelled out by <a href="bibliography.html#Andrews-83">[Andrews-83]</a>
-(function names updated, see historical note below):&nbsp;</p>
-
-<blockquote>
-
-<p>Although semaphores can be used to program almost any kind of synchronization,
-<b>down()</b> and <b>up()</b> are rather unstructured primitives, and so it is easy to err when using them. Execution of each critical section must begin with a
-<b>down()</b> and end with a <b>up()</b> (on the same semaphore). Omitting a <b>down()</b>
-or <b>up()</b>, or accidentally coding a <b>down()</b> on one semaphore and a <b>up()</b>
-on another can have disastrous effects, since mutually exclusive execution would no longer be ensured. Also, when using semaphores, a programmer can forget to include in critical sections all statements that reference shared objects. This, too, could destroy the mutual exclusion required within critical sections. A second difficulty with using semaphores is that both condition synchronization and mutual exclusion are programmed using the same pair of primitives. This makes it difficult to identify the purpose of a given
-<b>down()</b> or <b>up()</b> operation without looking at the other operations on the corresponding semaphore. Since mutual exclusion and condition synchronization are distinct concepts, they should have distinct notations.</p>
-
-</blockquote>
-
-<p><b>Historical note: </b>Dijkstra's original name for <b>down()</b> was <b>P</b>
-(short for the Dutch &quot;passeren&quot;, &quot;to pass&quot;), and for <b>up()</b>
-was <b>V</b> (short for the Dutch &quot;vrygeven&quot;, &quot;to release&quot;).</p>

-<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
-"thread of execution", and for definitions of threading related terms and of thread
-states such as "blocked".</p>
-
-<p>A thread of execution has an initial function. For the program'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 "finished" or "finished execution" 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 "joinable" or
-"non-joinable".</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>

-<h3>Constructors</h3>
-
-<pre>
-    thread();
-</pre>
-
-<p><b>Effects:</b> Constructs a <code>thread</code> object representing the current thread
-of execution.</p>
-
-<p><b>Postcondition:</b> <code>*this</code> is non-joinable.</p>
-
-<p><b>Danger:</b> <code>*this</code> is valid only within the current thread.</p>
-
-<pre>
-    thread(const <A href="../../function/index.html">boost::function0</A>&lt;void&gt;&amp; threadfunc);
-</pre>
-
-<p><b>Effects:</b> Starts a new thread of execution and constructs a <code>thread</code> object
-representing it.  Copies <code>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 thread of execution.</p>
-
-<p><b>Postcondition:</b> <code>*this</code> is joinable.</p>
-
-<p><b>Throws:</b> <code>boost::thread_resource_error</code> if a new thread of execution
-cannot be started.</p>
-
-<hr>
-<h3>Destructor</h3>
-
-<pre>
-    ~thread();
-</pre>
-
-<p><b>Effects:</b> Destroys <code>*this</code>. The actual thread of execution may
-continue to execute after the <code>thread</code> object has been destroyed.</p>
-
-<p><b>Notes:</b> If <code>*this</code> is joinable the actual thread of execution
-becomes "detached".  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>
-
-<hr>
-<h3>Comparison Operators</h3>
-
-<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>rhs</code>
-represent the same thread of execution.</p>
-
-<pre>
-    bool operator!=(const thread&amp; rhs);
-</pre>
-
-<p><b>Returns:</b>  <code>!(*this==rhs)</code>.</p>
-
-<hr>
-<h3>join</h3>
-
-<pre>
-    void join();
-</pre>
-
-<p><b>Requires:</b> <code>*this</code> is joinable.</p>
-
-<p><b>Effects:</b> The current thread of execution blocks until the initial function of
-the thread of execution represented by <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></p> If <code>*this == thread()</code> the result is implementation defined.
-If the implementation doesn't detect this the result will be
-<a href="definitions.html#Deadlock">deadlock</a>.</p>
-
-<hr>
-<h3>sleep</h3>
-
-<pre>
-    static void sleep(const <a href="xtime.html">xtime</a>&amp; xt);
-</pre>
-
-<p><b>Effects:</b> The current thread of execution blocks until <code>xt</code> is
-reached.</p>
-
-<hr>
-<h3>yield</h3>
-
-<pre>
-    static void yield();
-</pre>
-
-<p><b>Effects:</b> The current thread of execution is placed in the "ready" 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>
-
-<hr>
-<h2><a name="Example">Example Usage</a></h2>
-
-<pre>
-#include &lt;boost/thread/thread.hpp&gt;
-#include &lt;iostream&gt;
-
-struct thread_alarm
-{
-   thread_alarm(int secs) : m_secs(secs) { }
-   void operator()()
-   {
-       boost::xtime xt;
-       boost::xtime_get(&amp;xt, boost::TIME_UTC);
-       xt.sec += m_secs;
-
-       boost::thread::sleep(xt);
-
-       std::cout &lt;&lt; &quot;alarm sounded...&quot; &lt;&lt; std::endl;
-   }
-
-   int m_secs;
-};
-
-int main(int argc, char* argv[])
-{
-   int secs = 5;
-   std::cout &lt;&lt; &quot;setting alarm for 5 seconds...&quot; &lt;&lt; std::endl;
-   boost::thread thrd(thread_alarm(secs));
-   thrd.join();
-}
-</pre>
-
-<p>The output is:</p>
-
-<pre>
-setting alarm for 5 seconds...
-alarm sounded...

+[section:time Date and Time Requirements]
+
+As of Boost 1.35.0, the __boost_thread__ library uses the [link date_time Boost.Date_Time] library for all operations that require a
+time out. 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.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.get_system_time `boost::get_system_time()`]. e.g.
+
+    boost::system_time const timeout=boost::get_system_time() + boost::posix_time::milliseconds(500);
+
+    extern bool done;
+    extern boost::mutex m;
+    extern boost::condition_variable cond;
+
+    boost::unique_lock<boost::mutex> lk(m);
+    while(!done)
+    {
+        if(!cond.timed_wait(lk,timeout))
+        {
+            throw "timed out";
+        }
+    }
+
+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));
+    
+    boost::mutex m;
+    if(m.timed_lock(boost::posix_time::nanoseconds(100)))

+[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.
+
+
+[section:thread_specific_ptr Class `thread_specific_ptr`]
+
+    template <typename T>
