| My comment: |
|
If this function succeeds, the cursor will be positioned at an index entry that matches the requested location or offset.
If a record has been prepared for update, that update will be canceled. If an index range is in effect and JET_MoveFirst or JET_MoveLast was specified, that index range will be canceled. No change to the database state will occur. |
