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.
