Interfaces documented on this reference page conform to industry standards as follows:
IEEE Std 1003.1c-1995, POSIX System Application Program Interface
Mutex attributes object to be destroyed.
This routine destroys a mutex attributes object--that is, the object becomes uninitialized. Call this routine when your program no longer needs the specified mutex attributes object.
After this routine is called, DECthreads may reclaim the storage used by the mutex attributes object. Mutexes that were created using this attributes object are not affected by the destruction of the mutex attributes object.
The results of calling this routine are unpredictable, if the attributes object specified in the attr argument does not exist.
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 value specified by attr is invalid.
