!!NAME


daemon - run in the background
!!SYNOPSIS


__#include __


__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
BSD4.4.
