Function Documentation

int XCALL_DEF() x_pthread_mutex_unlock	(	pthread_mutex_t *	mutex,

Unlocks a mutex.

It safely unlocks a mutex by releasing the lock when the transaction commits.

Execution : deferred

Asynchronous failures : commit

Parameters:

[in]	mutex	The mutex to unlock.
[out]	result	Where to store any asynchronous failures.

Returns:

The new file descriptor on success, or -1 if a synchronous failure occurred (in which case, errno is set appropriately).
