Thread support library [[:Template:mark c++0x]]

The standard thread support library provides portable way to construct threads and to manage them.

Threads

Threads enable the program to execute across several processor cores.

Defined in header <thread>
thread	manages a separate thread (class)
Functions managing current thread
Defined in namespace this_thread
yield	hints the implementation to reschedule execution of threads (function)
get_id	returns the thread id of the current thread (function)
sleep_for	stops the execution of the current thread for a specified time duration (function)
sleep_until	stops the execution of the current thread until a specified time point (function)

Mutual exclusion

Several classes are provided that manage mutexes: mutex, recursive_mutex, timed_mutex, recursive_timed_mutex.

Several class templates are provided for generic mutex management: lock_guard, unique_lock.

once_flag

Several helper functions are provided for mutex locking:

Defined in header <mutex>
try_lock	tries to lock specified mutexes or locks, returns if at least one is unavailable (function)
lock	locks specified mutexes/locks, blocks if at least one is unavailable (function)
call_once	(function)
