Are there better ways to know if an item exists within the inventory of an object?

Ive been pondering this for awhile. Given LSL's astounding speed, I would really like an alternative to what Ive come up with. Im trying to create a function that tells me if an item is within the object's inventory from its name. Since there isnt a llIsInInventory function I thought of using llGetInventoryKey, then saw from the wiki page that it gets flaky with items that don't have full permissions. Then, llGetInventoryCreator, but then I read that it spams the public chat channel with an error if the inventory doesn't exist. llGetInventoryPermMask does the same. My final option: a for loop, iterating over every item in inventory.

Has anyone thought of anything else?

How about this. It first creates a list with the names of all items in the objects inventory. It then performs a ListFindList on it. So there's only 1 comparison to make...

integer Inventory_Search(string name)
{
     integer length = llGetInventoryNumber(INVENTORY_ALL);
     integer x;
     list inventory_names;     
     for (x=0;x<length;x++)
     {
          inventory_names += llGetInventoryName(INVENTORY_ALL,x);
     }
     integer found = llListFindList(inventory_names,(list)name);
     return found;
}

Here's what I have:

integer isInInventory(string name) {
    if (llGetInventoryKey(name) != NULL_KEY)
        return TRUE;
    integer i;
    integer num = llGetInventoryNumber(INVENTORY_ALL);
    for (i = 0; i < num; ++i) {
        if (llGetInventoryName(INVENTORY_ALL, i) == name)
            return TRUE;
    }
    return FALSE;
}

Chris, isn't that the same as this?

integer isInInventory(string name){
   	if (llGetInventoryKey(name) != NULL_KEY)
   		return TRUE;
   	return FALSE;
   }

I mean, it wouldn't actually ever return TRUE as a result of that FOR loop, would it?

llGetInventoryKey returns NULL_KEY when the item does not have full permissions. Looping through the inventory with llGetInventoryName should hit every item, no matter what its permissions.

Oh, right. It's been a long day.

I requested a function a few months back
integer llGetInventoryType(string name)
with the requirement that it doesn't return a verbal error when the item doesn't exist.

I was told it was going to be in 1.7
