tis_mutex_destroy(3)					     Library Functions Manual					      tis_mutex_destroy(3)

NAME

       tis_mutex_destroy - Destroys the specified mutex object.

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <tis.h>

       int   tis_mutex_destroy(
			      pthread_mutex_t	*mutex);

STANDARDS

       None

PARAMETERS

       Address of the mutex object (passed by reference) to be destroyed.

DESCRIPTION

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

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

       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 by mutex is invalid.  The caller does not have privileges to perform the operation.

ERRORS

       None

pthread_mutex_setname_np(3)				     Library Functions Manual				       pthread_mutex_setname_np(3)

NAME

       pthread_mutex_setname_np - Changes the object name in a mutex object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int   pthread_mutex_setname_np(
			     pthread_mutex_t	       *mutex,
			     const char 	       *name,
			     void		       *mbz);

PARAMETERS

       Mutex object whose object name is to be changed.  Object name value to copy into the mutex object.  Reserved for future use. The value must
       be zero (0).

DESCRIPTION

       This routine changes the object name in the mutex object specified by mutex to the value specified by name. To set  a  new  mutex  object's
       object name, call this routine immediately after initializing the mutex object.

       The object name is a C language string and provides an identifier that is meaningful to a person debugging a DECthreads-based multithreaded
       application. The maximum number of characters in the object name is 31.

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  mutex is invalid, or the length in characters of name exceeds 31.  Insufficient memory
       exists to create a copy of the object name string.

ERRORS

       None
