[fpc-devel] Packed record integers and x86_86

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;* *Refere

I think the official unsigned 32-bit integer type in Pascal is "LongWord". As others have said, be aware that pointers are 64-bit under x64... that's kind of why it's called x64!  If you absolutely must have a packed record with 32-bit types, I recommend changing Sender and Target to indices that
