void gtk_stock_add ( const GtkStockItem* items, guint n_items )
Registers each of the stock items in
items. If an item already
exists with the same stock ID as one of the
items, the old item
gets replaced. The stock items are copied, so GTK+ does not hold
any pointer into
items can be freed. Use
items is persistent and GTK+ need not
copy the array.
