C socket

I have been serching for a guide to unix C network programming everywhere but I have found only some tuorials, very useful but a little bit poors.

My question is if exist a network domain all over the world where C socket is treated with examples.
Programs i have looked into is hard to understand, They are too big .

Thanks

P.S. unix network programming by Stevens is too expensive for my pockets :o

Here is a free book on Linux programming. Sockets are covered with some examples.
