NAME pthread_cond_wait - wait on a condition variable CONTENTS Library Synopsis Description Return Values Errors See Also Standards LIBRARY .Lb libc_r .Lb libpthread .Lb libthr SYNOPSIS .In pthread.h int pthread_cond_wait "pthread_cond_t *cond" "pthread_mutex_t *mutex" DESCRIPTION The pthread_cond_wait function atomically blocks the current thread waiting on the condition variable specified by cond, and unblocks the mutex 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. RETURN VALUES If successful, the pthread_cond_wait function will return zero. Otherwise an error number will be returned to indicate the error. ERRORS The pthread_cond_wait function will fail if:
