std::recursive_mutex::unlock
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
Throws nothing.
Notes
unlock() is usually not called directly: std::unique_lock and std::lock_guard are used to manage exclusive locking.
