Starting application inside an application

[Horst Gassner]

Hello!

Platform: Linux

What is the easiest way to launch a new application from e.g. a menu in
a running application?
Using os.system() does not work because the calling application has to
wait until the launched application has terminated.

What I want to do is simply starting a second instance of my application
(just like starting the application from the command line a second
time). I am looking for a function like spawnv() which unfortunately
only works for the windows platform.

Thank you
Horst
