Thanks, but we've already had at least a dozen redundant answers to
this question. How many references to CRC32 implementations and zlib
do we need?
In any case I'm pretty sure the OP was looking for native code

I've got some old CRC code lying around.
Don't know if it's Intel/64bit clean though. Maybe someone want's to
check? :)

hi Angelo.
This is a trickier question than it sounds. The first thing is you
really have to understand is what you are after:
1) do you have an 8 bit, 16 bit or 32 bit CRC?
2) are you constrained to match someone else or is this just for your
comms?
3) are you going table driven (recom
