pthread_rwlock_unlock
pthread_rwlock_unlock(3C) Standard C Library Functions pthread_rwlock_unlock(3C)
NAME
pthread_rwlock_unlock - unlock read-write lock object
SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ]
#include <pthread.h>
int pthread_rwlock_unlock(pthread_rwlock_t *rwlock);
DESCRIPTION
The pthread_rwlock_unlock() function is called to release a lock held on the read-write lock object referenced by rwlock. Results are unde-
fined if the read-write lock rwlock is not held by the calling thread.
If this function is called to release a read lock from the read-write lock object and there are other read locks currently held on this
read-write lock object, the read-write lock object remains in the read locked state. If this function releases the calling thread's last
read lock on this read-write lock object, then the calling thread is no longer one of the owners of the object. If this function releases
the last read lock for this read-write lock object, the read-write lock object will be put in the unlocked state with no owners.
If this function is called to release a write lock for this read-write lock object, the read-write lock object will be put in the unlocked
state with no owners.
If the call to the pthread_rwlock_unlock() function results in the read-write lock object becoming unlocked and there are multiple threads
waiting to acquire the read-write lock object for writing, the scheduling policy is used to determine which thread acquires the read-write
lock object for writing. If there are multiple threads waiting to acquire the read-write lock object for reading, the scheduling policy is
used to determine the order in which the waiting threads acquire the read-write lock object for reading. If there are multiple threads
blocked on rwlock for both read locks and write locks, it is unspecified whether the readers acquire the lock first or whether a writer
acquires the lock first.
Results are undefined if any of these functions are called with an uninitialized read-write lock.
RETURN VALUES
If successful, the pthread_rwlock_unlock() function returns 0. Otherwise, an error number is returned to indicate the error.
