pthread_rwlock_unlock

PTHREAD_RWLOCK_UNLOCK(P)				     POSIX Programmer's Manual					  PTHREAD_RWLOCK_UNLOCK(P)

NAME

       pthread_rwlock_unlock - unlock a read-write lock object

SYNOPSIS

       #include <pthread.h>

       int pthread_rwlock_unlock(pthread_rwlock_t *rwlock);

DESCRIPTION

       The  pthread_rwlock_unlock()  function shall release a lock held on the read-write lock object referenced by rwlock.  Results are undefined
       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 last read lock for this
       read-write lock object, the read-write lock object shall 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 shall be put in the unlocked
       state.

       If there are threads blocked on the lock when it becomes available, the scheduling policy shall determine which thread(s) shall acquire the
       lock.	If the Thread Execution Scheduling option is supported, when threads executing with the scheduling policies SCHED_FIFO,  SCHED_RR,
       or  SCHED_SPORADIC are waiting on the lock, they shall acquire the lock in priority order when the lock becomes available. For equal prior-
       ity threads, write locks shall take precedence over read locks.	If the Thread Execution Scheduling option is not supported, it	is  imple-
       mentation-defined whether write locks take precedence over read locks.

       Results are undefined if any of these functions are called with an uninitialized read-write lock.

RETURN VALUE

       If successful, the pthread_rwlock_unlock() function shall return zero; otherwise, an error number shall be returned to indicate the error.

ERRORS

       The pthread_rwlock_unlock() function may fail if:

       EINVAL The value specified by rwlock does not refer to an initialized read-write lock object.

       EPERM  The current thread does not hold a lock on the read-write lock.

       The pthread_rwlock_unlock() function shall not return an error code of [EINTR].

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
