do what the fuck you want to

example program:

program that daemonizes, exits with signal number after receiving SIGINT, SIGHUP and SIGCHLD and just goes to minute sleeping forever

#include "daemonize.h"

void
sighandler(int signo) {
	exit(signo);
}

void
signalize(void) {
	signal(SIGINT, sighandler);
	signal(SIGHUP, sighandler);
	signal(SIGCHLD, sighandler);
}

void
main(void) {
	daemonize("/", 0000, signalize);
	while(1) sleep(60);
}
