.Sh SYNOPSIS
.Ft int
.Fn daemon "int nochdir" "int noclose"
.Sh DESCRIPTION
The
.Fn daemon
function makes the calling process into a daemon process: it forks and
continues as the child process (while the parent exits with a 0 exit value) ,
creates a new session, disassociates itself from the controlling terminal,
closes stdin, stdout and stderr (unless
.Fa noclose
is nonzero) and changes the working directory to the root directory (unless
.Fa nochdir
is nonzero).
.Sh RETURN VALUES
.Fn daemon
returns -1 if the fork failed, or 0 otherwise.
