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 that pair is stored 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 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, MovePrevDuplicate is successful, and any existing bytes are returned.
