NAME

       pthread_mutexattr_destroy - Destroys the specified mutex attributes object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_mutexattr_destroy(
			      pthread_mutexattr_t   *attr);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       IEEE Std 1003.1c-1995, POSIX System Application Program Interface

PARAMETERS

       Mutex attributes object to be destroyed.

DESCRIPTION

       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.

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 value specified by attr is invalid.

ERRORS

       None

NAME

       pthread_mutex_destroy - Destroys a mutex.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_mutex_destroy(
			      pthread_mutex_t	*mutex);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       IEEE Std 1003.1c-1995, POSIX System Application Program Interface

PARAMETERS

       The mutex to be destroyed.

DESCRIPTION

       This  routine  destroys	the specified mutex by uninitializing it, and should be called when a mutex object is no longer referenced.  After
       this routine is called, DECthreads may reclaim internal storage used by the specified mutex.

       It is safe to destroy an initialized mutex that is unlocked.  However, it is illegal to destroy a locked mutex.

       The results of this routine are unpredictable if the mutex object specified in the mutex argument does not currently exist, or is not  ini-
       tialized.

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.  An attempt was made to destroy the object referenced by mutex while it is locked or referenced.	The  value  speci-
       fied for mutex is invalid.

ERRORS

       None
