Hi,
Here's a sample code:
#include stdio.h
#include semaphore.h
int main(void) {
sem_t *dis_ping, *dis_pong;
dis_ping = sem_open(/ping.sem, O_CREAT, 0777, 1);
dis_pong = sem_open(/pong.sem, O_CREAT, 0777, 0);
for(;;) {
sem_wait(dis_ping);
puts(Ping...);

On FBSD 5.2, gcc first complains it doesn't know about O_CREAT...
That's not what the sem_open() manpage claims but, ok, let's include
