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...");
sem_post(dis_pong);
}sem_close(dis_ping); sem_close(dis_pong);
return 0; }
This code compiles and works fine on Darwin...
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 <fcntl.h>.
The code, then, compile ok, but fails on :
$ ./ping.exe zsh: invalid system call (core dumped) ./ping.exe
