those functions are provided to dupply the programmer with an easy interface
if he converts from the old GtkMenuFactory code. it is not guarranteed that
this interface will exist in 1.2 as well.
you should use the pure item factory functions/structures for this:

GtkItemFactoryEntry *entry = g_new (GtkItemFactoryEntry, 1);
entry->path = ...;
entry->accelerator = NULL;
entry->callback = new_pattern_selected;
entry->callback_action = 42;
entry->item_type = "<Item>";

gtk_item_factory_create_items (ifac, 1, entry, cb_data);

g_free (entry);

the callback will look like this:

void
new_pattern_selected (gpointer  cb_data,
                      guint     callback_action /* 42 */,
                      GtkWidget *widget /* menu item */)
{}
