What are the pros / cons of using pthread_cond_wait or using a semaphore ? I am waiting for a state change like this : pthread_mutex_lock(&cam->video_lock); while(cam->status == WAIT_DISPLAY) { pthread_cond_wait(&cam->video_cond, &cam->video_lock); } pthread_mutex_unlock(&cam->video_lock); Using a properly initialised semaphore, I think I could do it like this : while(cam->status == WAIT_DISPLAY) { sem_wait(&some_semaphore); } What are the pros and cons of each method ?
