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.

[edit] Notes

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