C++ sockets

[xicepik]

Hi. I'm learning C++ (i'm using kdevelop and i'm making "console" programs to begin with). I was searching a good tutorial on how to use socket with C/C++. I found a couple of pre-made libraries but I don't want "pre-made" things, I want to understand how they works.
Thanks

I dont have time to look through them, but maybe you can find something usefull.

A similar post in the python NG turned out this tutorial.

The BSD sockets API is exposed in perl/python/ruby. If you're familiar with any of these, a few throw-away experimental scripts might help you gain a quick understanding of the API.

The C-level API requires a lot of casting if I recall correctly. The thing that really (once) helped me understand it all is that the BSD library was designed as a multi-protocol one, not just tcpip. So the structure which represents a generic network address is slightly expanded to accomodate the notion of a tcp address, and when passing pointers to these, one needs to explicitly cast in C. In C++ proper objects can represent those notions and offer a cleaner interface. You can implement such a wrapper yourself once you've understood the underlying C-level API.
