    integer link_num = llGetNumberOfPrims();
    while (link_num > 1) // Check only child prims.
    {
        if (llGetLinkKey(link_num) == avatar) // If it is the avatar we want
        {
            return link_num; // then return the link number
        }
        --link_num; // else go on with next child.
    }
    // Avatar wasn't found
    return FALSE; // 0 (zero) for easy testing.
