I would like to know one more thing that I do not want to create more one instance of my daemon but I can create more than one. So how to prevent to create more than one instance. Is it possible to have only one instance for all users? If yes then how. Regards On Mon, Jan 12, 2009 at 7:59 PM, Jason Coco <jason.coco@gmail.com> wrote:

Hi Jason,

Thanks but I knew this thing. Is there any other way to do the same thing only on the basis of name of daemon application.

I think we can not do even by using StartupItems.

Using the dot notation for your daemon is just the suggested form (although it's suggested for a good reason). You can use whatever label you wish. Just make the label in the plist the same as the name of the daemon and then you can start and stop it using just the daemon's name.

launchctl start mydaemon launchctl stop mydaemon

That's basically the way it's done. If you want to give users something else to start and stop the daemon, you can create a simple script that calls launchctl. For example:

#!/bin/bash

case "$1" in

start) /bin/launchctl start com.mycompany.mydaemon.daemon # use whatever label is in the plist ;;

stop) /bin/launchctl stop com.mycompany.mydaemon.daemon ;;

restart) /bin/launchctl stop com.mycompany.mydaemon.daemon ;;

status) if (/bin/launchctl list | grep com.mycompany.mydaemon.daemon >/dev/null); then echo Daemon is running else echo Daemon is not running fi ;;

*) echo "Usage $0 { stop|start|restart|status } exit 1

esac

You can also write an application which uses the launchd api to programatically start and stop the daemon. This way you could write a little gui app to control it or a system panel to toggle it on or off. If you wish to do it this way, see the API in /usr/include/launch.h

HTH, Jason
