임베디드에 cron을 돌리려고 하는데...

        switch (fork()) {
        case -1:
            log_it("CRON",getpid(),"DEATH","can't fork");
            exit(0);
            break;
        case 0:
            /* child process */
            log_it("CRON",getpid(),"STARTUP","fork ok");
            (void) setsid();
            break;
        default:
            /* parent process should just die */
            _exit(0);
        }
