pthread_mutex_destroy(3)			      pthread_mutex_destroy(3)

NAME
       pthread_mutex_destroy - Destroys a mutex

SYNOPSIS
       #include <pthread.h>

       int pthread_mutex_destroy(
	       pthread_mutex_t *mutex );

LIBRARY
       DECthreads POSIX 1003.1c Library (libpthread.so)

STANDARDS
       Interfaces  documented on this reference page conform to industry stan‐
       dards 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 spec‐
       ified  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  ref‐
       erenced by mutex while it is locked or referenced.  The value specified
       for mutex is invalid.

ERRORS
       None
