mtx_unlock - cppreference.com (original) (raw)
Unlocks the mutex pointed to by mutex.
The behavior is undefined if the mutex is not locked by the calling thread.
This function synchronizes-with subsequent mtx_lock, mtx_trylock, or mtx_timedlock on the same mutex. All lock/unlock operations on any given mutex form a single total order (similar to the modification order of an atomic).
[edit] Parameters
| mutex | - | pointer to the mutex to unlock |
|---|
[edit] Return value
thrd_success if successful, thrd_error otherwise.
