tis_mutex_unlock(3)					     Library Functions Manual					       tis_mutex_unlock(3)

NAME

       tis_mutex_unlock - Unlocks the specified mutex.

LIBRARY

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

SYNOPSIS

       #include <tis.h>

       int   tis_mutex_unlock(
			      pthread_mutex_t	*mutex);

STANDARDS

       None

PARAMETERS

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

DESCRIPTION

       This routine unlocks the specified mutex mutex.

       For more information about actions taken when threads are present, refer to the pthread_mutex_unlock 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 value specified by mutex is invalid.  The caller does not own the mutex.

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
