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.

FreeBSD 4.10                     June 9, 1993                     FreeBSD 4.10
