If the previous key/data pair of the database is a duplicate data
            record for the current key/data pair, the cursor is moved to the
            previous key/data pair of the database, and the secondary key and
            primary key/data pair in Current. MovePrevDuplicate
            will return false if the previous key/data pair of the database is
            not a duplicate data record for the current key/data pair. If
            key, or pkey, or
            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, MovePrevDuplicate is successful, and any existing
            bytes are returned.
