If the cursor is not yet initialized, MovePrevUnique is identical to 
            MoveLast(LockingInfo). Otherwise, move the cursor to
            the previous non-duplicate key in the database, and store that key
            and associated datum in Current. MovePrevUnique will
            return false if no non-duplicate key/data pairs exist after the
            cursor position in the database. If either the key or the data
            is partial DatabaseEntry, its
            PartialLen bytes starting
            PartialOffset bytes from the beginning
            of the retrieved data record are returned as if they comprised the
            entire record. If any or all of the specified bytes do not exist
            in the record, MovePrevUnique is successful, and any existing
            bytes are returned.
