||||
|

Deprecated features since boost 1.50 available only until boost 1.55:
|
||||
|
||||
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_V2_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_V2_0_0. These deprecated features will be only available until boost 1.55, that is you have 1 year and a half to move to the new features.
|
||||
|
||||
* Time related functions don't using the Boost.Chrono library, use the chrono overloads instead.
|
||||
|
||||
Breaking changes:
|
||||
|
||||
There are some new features which share the same interface but with different behavior. These breaking features are not provided by default when BOOST_THREAD_VERSION is 2, but the user can however choose the version 1 behavior by defining the corresponding macro. As for the deprecated features, these broken features will be only available until boost 1.55.

[heading 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.
|
||||
|
||||

Almost every line of code in __boost_thread__ has been changed since the 1.34 release of boost. However, most of the interface

|
||||
* 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.

[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 `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.
|
||||
|
||||
You can wait for futures either individually or with one of the __wait_for_any__ and __wait_for_all__ functions.

[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.

||||

||||

|

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;
|

[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.

__boost_thread__ enables the use of multiple threads of execution with shared data in portable C++ code. It provides classes and

functions for managing the threads themselves, along with others for synchronizing data between the threads or providing separate

copies of data specific to individual threads.

either include the specific headers specified by the descriptions of

each class or function, or include the master thread library header:

[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.

[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)))
