- The easiest way is to use streams. Here's a sketch:
-
- }
-
- Uses
- Objects;
-
- Var
- S : TDosStream;
- data : Array[1..1000] of Byte; { Big enough For anything }
- Position : LongInt; { The position of the item }
- Size : Word; { The size of the item }
- begin
- S.init('dataFile',stOpenRead);
-
- { Now determine Position and Size from the other File somehow }
-
- S.Seek(Position);
- S.Read(data,Size);
- if S.Status <> stOK then
- begin
- Writeln('Stream error ',S.Status,' With error info ',S.ErrorInfo);
- S.Reset;
- end;
- end.
