Just a footnote:
a couple of years ago I wrote a set of preprocessor macros that hide the
details
of byte swapping from the user in a very convenient way: once you have
set an
indicator if to swap bytes or not, you simply use macros like SHORT,
USHORT, LONG,
ULONG, INT, etc, like
long a,b;
short s;
/*...*/
if (s == SHORT(0x00fe))
a = LONG(LONG(b) + 5;
etc.
If there is interest, I may post that stuff.
