Re: [LIP] check instance of a running application

Shared Memory between instances.good Idea.Let me try
that.

Apart from writing to a File for instance checking, 

what does the command does.. 
killall -9 myapplication  

If i want to implement this way thr code what should i
do to kill the application  by just passing the
application name without using exec or system
command.Just want to know the other approach.
