MirOS Manual: pthread_cond_wait(3)

PTHREAD_COND_WAIT(3)       BSD Programmer's Manual        PTHREAD_COND_WAIT(3)


     pthread_cond_wait - wait on a condition variable


     #include <pthread.h>

     pthread_cond_wait(pthread_cond_t *cond, pthread_mutex_t *mutex);


     The pthread_cond_wait() function atomically blocks the current thread
     waiting on the condition variable specified by cond, and unblocks the mu-
     tex specified by mutex. The waiting thread unblocks only after another
     thread calls pthread_cond_signal(3), or pthread_cond_broadcast(3) with
     the same condition variable, and the current thread reacquires the lock
     on mutex.


     If successful, the pthread_cond_wait() function will return zero. Other-
     wise an error number will be returned to indicate the error.


     pthread_cond_wait() will fail if:

     [EINVAL]      The value specified by cond or the value specified by mutex
                   is invalid.


     pthread_cond_broadcast(3), pthread_cond_destroy(3), pthread_cond_init(3),
     pthread_cond_signal(3), pthread_cond_timedwait(3)


     pthread_cond_wait() conforms to ISO/IEC 9945-1:1996 ("POSIX").
