It doesn't look like it's documented anywhere, but the function  
prototype that you want to be matching is:
	void callback(PurpleBlistNode*, gpointer cb_data)

See, for example, gtkutils.c:menu_action_cb:
	static void
	menu_action_cb(GtkMenuItem *item, gpointer object)
	{
	    gpointer data;
	    void (*callback)(gpointer, gpointer);

	    callback = g_object_get_data(G_OBJECT(item), "purplecallback");
	    data = g_object_get_data(G_OBJECT(item), "purplecallbackdata");

	    if (callback)
	        callback(object, data);
	}

(in your case, you'd have (PurpleBlistNode*)buddy and menu_action->data)
