C++ reading

there is no good way to use sockets in C++. it's all dusty old C code.
wait for the networking TS.

1. there's no need for "C++ socket programming under linux". Sockets are a C library, no need to add '++'
2. Socket programming is best documented by the manpages. It is the ultimate documentation resource, and the interface has been consistent since decades. Lookup manpages for socket(2), bind(2), listen(2), accept(2), connect(2), ip(7), socket(7), tcp(7), udp(7), recv(2), send(2), read(2), write(2) and it should get you going for basic socket programming. (in case you don't know, numbers represent the manpage category, so just type 'man 7 socket' if you want to read socket(7) manpage). Add getaddrinfo(3) for name resolution. The manpages include basic examples, and you can find plenty online. A book is seldom necessary, but you can take >>60233611 or "Advanced UNIX Programming" - very old books (from the 80's) that are still fully valid today since basis UNIX API doesn't change that much
3. The real deal with network programming aren't the sockets themselves, but the asynchronous I/O. You need to learn about things like poll(2) (or select(2), that is a bit simpler, but poll is preferable). For more complex applications, you should look into event frameworks, libraries that abstract a lot of things for you, but for simple things just using basic functions is easier.
4. Keep in mind that all these functions are VERY generic (unlike Windows) and work the same way for very different protocols and socket types. You can work with raw IP sockets, or TCP, or Ethernet, or with terminals, UNIX domain sockets, files using same functions.
5. For more higher-layer protocols like HTTP, look into libraries like libcurl(3)

Wow, thanks a lot guys. I really interested in making something network related but i have no idea at all.
