you have two choices. you can either attach callbacks
to the select_row (and unselect_row) signals, or you
can poke about with the selection field:

	GtkWidget * clist = <get hold of clist>
	
	GList * items = GTK_CLIST(clist)->selection;
	
	for (; items != NULL; items = items->next) {
		int row = GPOINTER_TO_INT(items->data);
		<do something to this row>
	}

both are rather nasty, in one way or another. which is
better depends on your application, though using the
signals means you can avoid poking about with the
widget's implementation at the cost of keeping your
own model of row selection.
