Help, daemon process failed!

Joran · 08-01-2003, 08:43 PM

I writed a daemon program, using the daemon_init() function, giving by the UNIX Network Programming Vol1[Stevens 1998]. But
it exited after this function was called! And when I debuged it with
gdb, I found it exited normally just in this call. Even did the daemon() system call!
I'm very puzzled. Could someone who give me an explaination for detail?
Thanks a lot!

P.S. My kernel is 2.4.18-14(RH8.0)

And that is the code:

Code:

void daemon_init(/*const char* pname, int facility*/)
{
	int i;
	pid_t pid;

	if ((pid = fork()) != 0)
		exit(0);

	setsid();
	
	signal(SIGHUP, SIG_IGN);

	if ((pid = fork()) != 0)
		exit(0);

	/*daemon_proc = 1;*/

	chdir("/");

	umask(0);

	for (i = 0; i < MAXFD; i++)
		close(i);

	/*open(pname, LOG_PID, facility);*/
}
