[Winpcap-users] TCP/IP stack - reinventing the wheel

[Ramiro Polla]

Hello,

It is meant for embedded hardware. But it does communicate well with any 
other TCP/IP stack.

The code is very generic and simple (always uses 8-bit bytes, no words or 
dwords) so that it will compile on most non-C-compliant proprietary 
compilers. Gcc optimizes it very well. It does a good job on finding out 
what could be 32-bit and making it good for the processor.

I`d say It`s worth the try.
