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
