| class timed_mutex; |
(since C++11) | |
The timed_mutex class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads.
In a manner similar to mutex, timed_mutex offers exclusive, non-recursive ownership semantics. In addition, timed_mutex provides the ability to attempt to claim ownership of a timed_mutex with a timeout via the member functions try_lock_for() and try_lock_until().
The timed_mutex class satisfies all requirements of TimedMutex and StandardLayoutType.

not copy-assignable (public member function) |
Locking | |
| locks the mutex, blocks if the mutex is not available (public member function) | |
| tries to lock the mutex, returns if the mutex is not available (public member function) | |
| tries to lock the mutex, returns if the mutex has been unavailable for the specified timeout duration (public member function) | |
| tries to lock the mutex, returns if the mutex has been unavailable until specified time point has been reached (public member function) | |
| unlocks the mutex (public member function) | |
Native handle | |
| returns the underlying implementation-defined native handle object (public member function) | |
