SYNOPSIS
     #include <pthread.h>

     int
     pthread_rwlockattr_setpshared(pthread_rwlockattr_t	*attr, int pshared);

DESCRIPTION
     The pthread_rwlockattr_setpshared() function sets the process shared
     attribute of attr to the value referenced by pshared.  The	pshared	argu-
     ment may be one of	two values:

     PTHREAD_PROCESS_SHARED   Any thread of any	process	that has access	to the
			      memory where the read/write lock resides can
			      manipulate the lock.

     PTHREAD_PROCESS_PRIVATE  Only threads created within the same process as
			      the thread that initialized the read/write lock
			      can manipulate the lock.	This is	the default
			      value.

RETURN VALUES
     If	successful, the	pthread_rwlockattr_setpshared()	function will return
     zero.  Otherwise an error number will be returned to indicate the error.
