 ---Returns information about an item, by name, link or id. Will only return item information if it is directly available in memory. An item is present in memory if:    It has been seen this session, OR   It's present in Cache/enUS/Item-sparse.dba, where enUS is the user's locale  If item information is not readily available, the client will first look on disk in DBFilesClient/Item-sparse.db2. If an item is found there, the client fires the GET_ITEM_INFO_RECEIVED event and keeps the result in memory for further GetItemInfo requests. If an item is not found on disk either, the client will send a server request for it. If the request fails, nothing happens. If the request succeeds, the client stores the item in memory and writes it to Cache/Locale/Item-sparse.dba. The client will never send more than one server request per id per session.

 ---Returns a unit's class. The second return (classFileName) can be used for locale-independent verification of a unit's class, or to look up class-related data in various global tables:    RAID_CLASS_COLORS provides a standard color for each class (as seen in the default who, guild, calendar, and raid UIs)   CLASS_ICON_TCOORDS provides coordinates to locate each class' icon within the "Interface\Glues\CharacterCreate\UI-CharacterCreate-Classes" texture  For non-player units, the first return (class) will be the unit's name; to always get a localized class name regardless of unit type, use UnitClassBase instead.
