How about defining something more pascalish first, a record type for
example:
i would agree with this since it is more readable ;)
{$modeswitch autoderef}
type
PDataHeader = ^TDataHeader;
TDataHeader = record
sequence_crc: QWord;
sequence_key: QWord;
compr_crc: QWord;
compr_len: DWord;
end;
and it looks like here you did see and allow for 64bit on the first
three and 32bit on the last one...
When you declare the record properly:
TDataHeader = record
sequence_crc_Ptr,
sequence_key_Ptr,
compr_crc_Ptr: PInt64;
compr_len_Ptr: PLongInt;
end;
then its size depends on the size of an pointer. In 32 bit code the
record size will be 16 bytes, in 64 bit code 32 bytes. But since the
incoming data array has a fixed alignment, more wizardry is required to
match precisely that layout in OPL.
