pthread_rwlock_destroy
pthread_rwlock_destroy(3) Library Functions Manual pthread_rwlock_destroy(3)
NAME
pthread_rwlock_destroy - Destroys a read-write lock object.
LIBRARY
DECthreads POSIX 1003.1c Library (libpthread.so)
SYNOPSIS
#include <pthread.h>
int pthread_rwlock_destroy(
pthread_rwlock_t *rwlock);
PARAMETERS
Address of the read-write lock object to be destroyed.
DESCRIPTION
This routine destroys the specified read-write lock object by uninitializing it, and should be called when the object is no longer refer-
enced in your program. After this routine is called, DECthreads may reclaim internal storage used by the specified read-write lock object.
The effect of subsequent use of the lock is undefined until the lock is reinitialized by another call to pthread_rwlock_init.
It is illegal to destroy a locked read-write lock.
The results of this routine are unpredictable if the specified read-write lock object does not currently exist or is not initialized. This
routine destroys the read-write lock object specified by the rwlock argument and releases any resources that the object used.
A destroyed read-write lock object can be reinitialized using the pthread_rwlock_init(3) routine. The results of otherwise referencing a
destroyed read-write lock object are undefined.
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 rwlock while it is locked or referenced.
ERRORS
None
