mtx_unlock
Defined in header <threads.h> | ||
---|---|---|
int mtx_unlock( mtx_t *mutex ); | (since C11) |
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).
Parameters
mutex | - | pointer to the mutex to unlock |
Return value
thrd_success
if successful, thrd_error
otherwise.
