If the cursor is not yet initialized, MoveNext is identical to
MoveFirst(LockingInfo). Otherwise, move the cursor to
the next key/data pair of the database, and store that pair in
Current. In the presence of duplicate key values, the
value of Current.Key may not change.
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, MoveNext is successful, and any existing bytes are
returned.
