Hello, does sem_post wake up another thread and preempt the current thread if the other thread has a higher priority than the current one? thread A : prio 10 thread B : prio 20 thread B : wait (sem) thread A : running thread A : post (sem) thread B : now running? I have written an example and it seems, that thread B will not preempt thread A.
