replace the item at the current cursor position. The key parameter must still be provided, and must match it. If using sorted duplicates (MDB_DUPSORT) the data item must still sort into the same place. This is intended to be used when the new data is the same size as the old. Otherwise it will simply perform a delete of the old record followed by an insert.
