std::recursive_timed_mutex::unlock: std::recursive_timed_mutex::unlock

NAME

std::recursive_timed_mutex::unlock - std::recursive_timed_mutex::unlock

Synopsis


void unlock(); (since C++11)


Unlocks the mutex if its level of ownership is 1 (there was exactly one more call to lock() than there were calls to unlock() made by this thread), reduces the level of ownership by 1 otherwise.
The mutex must be locked by the current thread of execution, otherwise, the behavior is undefined.
This operation synchronizes-with (as defined in std::memory_order) any subsequent lock operation that obtains ownership of the same mutex.

Parameters


(none)

Return value


(none)

Exceptions


(none)

Notes


unlock() is usually not called directly: std::unique_lock and std::lock_guard are used to manage exclusive locking.
