Function Documentation

int XCALL_DEF() x_pthread_mutex_lock	(	pthread_mutex_t *	mutex,

Locks a mutex.

It safely locks a mutex by releasing the lock if the transaction aborts.

Execution : in-place

Asynchronous failures : abort

Parameters:

[in]	mutex	The mutex to lock.
[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).
