Not quite sure what you're asking, but if you're looking for a C 
cross-platform library for doing TCP/IP, then look no further than 
Berkeley Sockets. They're the de facto standard. If a particular 
platform has *any* cross-platform TCP/IP library implemented, you can 
bet it's Berekely Sockets.

Berkeley Sockets is also called "BSD sockets". I remember doing some 
googling/wikipedia'ing to find out what the craic was with the name... 
but I never got a straight answer.

Anyway, if you wanna go with Berkeley Sockets, here's your first stop:
