std::timed_mutex - cppreference.com (original) (raw)
| | | | | ------------------- | | ------------- | | 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.
