how to make a application instance unique ?

[Aaron Lewis <the warl0ck 1989 gmail com>]

Hi,
	I'm new to GTK+ world , and is there any ways to ensure that only
single instance of a GTK+ application running ?

	i.e	If another application tries to run , former instance should show up
	( if hide to system tray ) or get focus.

	Appreciate any of your response ;-)
