pthread_mutex_lock -- lock a mutex 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
pthread_mutex_lock() will fail if: [EDEADLK] A deadlock would occur if the thread blocked waiting for mutex. [EINVAL] The value specified by mutex is invalid. SEE ALSO
pthread_mutex_destroy(3), pthread_mutex_init(3), pthread_mutex_trylock(3), pthread_mutex_unlock(3) STANDARDS
pthread_mutex_lock() conforms to ISO/IEC 9945-1:1996 (``POSIX.1''). BSD
