PTHREAD_MUTEX_UNLOCK(3)	 BSD Library Functions Manual  PTHREAD_MUTEX_UNLOCK(3)

NAME
     pthread_mutex_unlock -- unlock a mutex

LIBRARY
     POSIX Threads Library (libpthread,	-lpthread)

SYNOPSIS
     #include <pthread.h>

     int
     pthread_mutex_unlock(pthread_mutex_t *mutex);

DESCRIPTION
     If	the current thread holds the lock on mutex, then the
     pthread_mutex_unlock() function unlocks mutex.

     If	the argument pointed by	the mutex is a robust mutex in the inconsis-
     tent state, and the call to pthread_mutex_consistent() function was not
     done prior	to unlocking, further locking attempts on the mutex mutex are
     denied and	locking	functions return ENOTRECOVERABLE error.

RETURN VALUES
     If	successful, pthread_mutex_unlock() will	return zero, otherwise an er-
     ror number	will be	returned to indicate the error.

ERRORS
     The pthread_mutex_unlock()	function will fail if:

     [EINVAL]		The value specified by mutex is	invalid.

     [EPERM]		The current thread does	not hold a lock	on mutex.

SEE ALSO
     pthread_mutex_destroy(3), pthread_mutex_init(3), pthread_mutex_lock(3),
     pthread_mutex_trylock(3)

STANDARDS
     The pthread_mutex_unlock()	function conforms to ISO/IEC 9945-1:1996
     ("POSIX.1").
