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
     &nb
