std::timed_mutex
 
Defined in header <mutex>
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.
