std::recursive_timed_mutex::unlock
< cpp | thread | recursive timed mutex
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.
