tis_unlock_global(3)					     Library Functions Manual					      tis_unlock_global(3)

NAME

       tis_unlock_global - Unlocks the DECthreads global mutex.

LIBRARY

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

SYNOPSIS

       #include <tis.h>

       int   tis_unlock_global(void);

STANDARDS

       None

PARAMETERS

       None

DESCRIPTION

       This  routine  unlocks  the  DECthreads	global	mutex.	 Because  the  global  mutex  is  recursive,  the  unlock occurs when each call to
       tis_lock_global(3) has been matched by a call to this routine.  For  example,  if  your	program  called  tis_lock_global(3)  three  times,
       tis_unlock_global(3) unlocks the global mutex when you call it the third time.

       For more information about actions taken when threads are present, refer to the pthread_unlock_global_np()(3) description.

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 DECthreads global mutex is unlocked or locked by another thread.

ERRORS

       None

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
