Try using a structure instead, it would be able to contain multiple
arrays with totals.  But in either case you choose you should
allocate the pointer array or structure and then passing it
to the callback.


mystruct *data = (mystruct *)g_malloc0(sizeof(mystruct));

/* Fill up the data structure here. */

gtk_signal_connect(
 GTK_OBJECT(btn), "clicked",
 myclickedcallback, data
);
/* Don't forget to destroy it when the widget is destroyed. */
gtk_signal_connect(
 GTK_OBJECT(btn), "destroy",
 mydestroycallback, data
);
