Hi,

I've done some digging as well:

int main() {
sem_t sem;
struct timespec ts = {0, 0};
if (sem_init(&sem, 0, 0) == -1) {
        perror ("sem_init");
        return -1;
}
if (sem_timedwait(&sem, &ts)==-1) {
        perror ("sem_timedwait");
        return -2;
}
return 0;
}

sem_timedwait: Connection timed out

>From what I got from the manpages, ts should probably be initialized
as I've done above. What seems to work is to initialize the semaphore
to 1, but then I have absolutely no experience with semaphores, nor
what this test should actually test.
