-.SH NAME
-daemon \- run in the background
-.SH SYNOPSIS
-.B #include <unistd.h>
-.sp
-.BI "int daemon(int " nochdir ", int " noclose );
-.sp
-.in -4n
-Feature Test Macro Requirements for glibc (see
-.BR feature_test_macros (7)):
-.in
-.sp
-.BR daemon ():
-_BSD_SOURCE || (_XOPEN_SOURCE && _XOPEN_SOURCE\ <\ 500)
-.SH DESCRIPTION
-The
-.BR daemon ()
-function is for programs wishing to detach themselves from the
-controlling terminal and run in the background as system daemons.
-.PP
-If
-.I nochdir
-is zero,
-.BR daemon ()
-changes the calling process's current working directory
-to the root directory ("/");
-otherwise, the current working directory is left unchanged.
-.PP
-If
-.I noclose
-is zero,
-.BR daemon ()
-redirects standard input, standard output and standard error
-to
-.IR /dev/null ;
-otherwise, no changes are made to these file descriptors.
-.SH RETURN VALUE
-(This function forks, and if the
-.BR fork (2)
-succeeds, the parent calls
-.\" not .IR in order not to underline _
-.BR _exit (2),
-so that further errors are seen by the child only.)
-On success
-.BR daemon ()
-returns zero.
-If an error occurs,
-.BR daemon ()
-returns \-1 and sets
-.I errno
-to any of the errors specified for the
-.BR fork (2)
-and
-.BR setsid (2).
-.SH ATTRIBUTES
-.SS Multithreading (see pthreads(7))
-The
-.BR daemon ()
-function is thread-safe.
-.SH CONFORMING TO
-Not in POSIX.1-2001.
-A similar function appears on the BSDs.
-The
-.BR daemon ()
-function first appeared in 4.4BSD.
-.SH NOTES
-The glibc implementation can also return \-1 when
-.I /dev/null
-exists but is not a character device with the expected
-major and minor numbers.
-In this case,
-.I errno
-need not be set.
-.SH SEE ALSO
-.BR fork (2),
-.BR setsid (2)
-.SH COLOPHON
-This page is part of release 3.79 of the Linux
-.I man-pages
-project.
-A description of the project,
-information about reporting bugs,
