Data Item Count
After a cursor has been initialized to reference a particular key in the database, it can be used to determine the number of data items that are stored for any particular key. The DBcursor→c_count method returns this number of data items. The returned value is always one unless the database supports duplicate data items; it then may be any number of items.
