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. 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

pthread_mutex_lock -- lock a mutex LIBRARY
POSIX Threads Library (libpthread, -lpthread) SYNOPSIS
#include <pthread.h> int pthread_mutex_lock(pthread_mutex_t *mutex); DESCRIPTION
The pthread_mutex_lock() function locks mutex. If the mutex is already locked, the calling thread will block until the mutex becomes avail- able. RETURN VALUES
If successful, pthread_mutex_lock() will return zero, otherwise an error number will be returned to indicate the error. ERRORS
The pthread_mutex_lock() function will fail if: [EINVAL] The value specified by mutex is invalid. [EDEADLK] A deadlock would occur if the thread blocked waiting for mutex. SEE ALSO
