Beej's Guide to Network Programming
Using Internet Sockets
Hello, one and all! This is my little how-to guide on network programming using Internet sockets, or "sockets programming", for those of you who prefer it. The sockets API, though started by the Berkeley folk, has been ported to many many platforms, including Unix, Linux, and even Windows.
Unfortunately, it can be a little, um, "much" to digest the API, but as long as you know some C or C++, this guide should springboard you into the realm of network programming with hopefully as little hassle as humanly possible!
