Hi there,
I need a solution for a packed record containing 4-byte 32-bit integers and
cardinals, and other byte 8 bit and word 16 bit sized variables to overlay
over a stream.
Example:
*type*
* TMyBinaryHeader = packed record*
* Sender : Cardinal;*
* Target : Cardinal;*
* Reference : Integer; *
* Flags : Word;*
* CheckByte : Byte;*
* end;*
So on 32 bit systems, SizeOf(TMyBinaryHeader) will report 15 bytes. How do
I accomplish this on 64 bit platform and avoiding "myprotocollib.pas(x,y)
Error: Typecast has different size (4 -> 8) in assignment" without having
to port to ugly byte copy operations.
Thanks.
