       daemon(nochdir, 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
       The function daemon may fail and set errno for any of the errors specified for the library functions fork(2).

SEE ALSO
       fork(2), ioctl(2).

HISTORY
       The daemon function first appeared in 4.4BSD.
