DESCRIPTION

This routine attempts to lock the specified mutex mutex. When this routine is called, an attempt is made immediately to lock the mutex. If the mutex is successfully locked, zero (0) is returned.

If the specified mutex is already locked when this routine is called, the caller does not wait for the mutex to become available. [EBUSY] is returned, and the thread does not wait to acquire the lock.

 

RETURN VALUES

If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows: Successful completion. The mutex is already locked; therefore, it was not acquired. The value specified by mutex is invalid.
