i think you are wrong, first the theory:

 - in the 'prog' structure it is also passed a file name of an application
   which will be started on button-click. until now it works fine.
   if there would be an argument before the 'prog' argument a segmention
   fault would be very likely (strings are more dangerous than just an
   integer, isn't it?)

and then the praxis:

 - i've changed my code as you said, but now i get a segmention fault
   while accessing the strings in the 'prog' structure.. so i think
   the gpointer from the gtk_signal_connect() is as i had it first the
   SECOND argument in the callback!

 - my question still lives: is there a third argument or not? is that
   the event?

the function is connected via:

gtk_signal_connect (GTK_OBJECT(button), "clicked",
        GTK_SIGNAL_FUNC(button_clicked), (void *) prog);
