DAEMON(3)	       FreeBSD Library Functions Manual		     DAEMON(3)

NAME
     daemon -- run in the background

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <stdlib.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 standard
     input, standard output and	standard error to ``/dev/null''.

ERRORS
     If	an error occurs, daemon() returns -1 and sets the global variable
     errno to any of the errors	specified for the library functions fork(2)
     and setsid(2).

SEE ALSO
     fork(2), setsid(2)

HISTORY
     The daemon() function first appeared in 4.4BSD.
