NAME
pthread_mutex_unlock -- unlock a mutex
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. Calling pthread_mutex_unlock() with a mutex that the calling thread does not hold will result in undefined behavior.
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'').
