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 try_lock_for() and try_lock_until() methods.

The timed_mutex class satisfies all requirements of TimedMutex and StandardLayoutType.

Member types

Member type	Definition
native_handle_type(optional)	implementation-defined

Member functions

(constructor)	constructs the mutex (public member function)
(destructor)	destroys the mutex (public member function)
operator= [deleted]	not copy-assignable (public member function)
Locking
lock	locks the mutex, blocks if the mutex is not available (public member function)
try_lock	tries to lock the mutex, returns if the mutex is not available (public member function)
try_lock_for	tries to lock the mutex, returns if the mutex has been unavailable for the specified timeout duration (public member function)
try_lock_until	tries to lock the mutex, returns if the mutex has been unavailable until specified time point has been reached (public member function)
unlock	unlocks the mutex (public member function)
Native handle
native_handle	returns the underlying implementation-defined native handle object (public member function)
