Is there any POSIX or Mac function which leaves the object signaled like SetEvent() in Win32? Counting semaphore will not fit in my case. typedef struct _persistent_event { pthread_cond_t cond; pthread_mutex_t mutex; int isset; } t_persistent_event; t_persistent_event *NewEvent(void) { t_persistent_event *event = malloc(sizeof(*event)); pthread_cond_init(&event->condvar, NULL); pthread_mutex_init(&event->mutex, NULL); event->isset=0; return event; } void SetEvent(t_persistent_event *event) { pthread_mutex_lock(&event->mutex); event->isset=1; pthread_cond_signal(&event->cond); pthread_mutex_unlock(&event->mutex); } void WaitEvent(t_persistent_event *event) { pthread_mutex_lock(&event->mutex); while (!event->isset) pthread_cond_wait(&event->condvar,&event->mutex); event->isset=0; pthread_mutex_unlock(&event->mutex); } ResetEvent() and DestroyEvent() left as an exercise to the reader.
