PTHREAD_MUTEX_UNLOCK(3) 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_un- lock() function unlocks mutex. If the argument pointed by the mutex is a robust mutex in the inconsistent 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 error 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").
