NAME
daemon - run in the background
SYNOPSIS
#include <unistd.h>
int daemon(int nochdir, int noclose);
DESCRIPTION
The daemon() function is for programs wishing to detach themselves
from the controlling terminal and run in the background as system
daemons.
Unless the argument nochdir is non-zero, daemon() changes the current
working directory to the root ("/").
Unless the argument noclose is non-zero, daemon() will redirect stan-
dard input, standard output and standard error to /dev/null.
RETURN VALUE
(This function forks, and if the fork() succeeds, the parent does
_exit(0), so that further errors are seen by the child only.) On
success zero will be returned. If an error occurs, daemon() returns
