WoW:API GetLootSlotLink

Returns loot slot items link for input into chat frames or any textual display. The example below will insert the items link into your chat text box while you're typing. Note, this obviously doesn't work with Macro's as they clear your chat buffer.

   for index = 1, GetNumLootItems(), 1 do
     if (LootSlotIsItem(index)) then
       local iteminfo = GetLootSlotLink(index);
       ChatFrameEditBox:Insert(iteminfo);
     end
   end
