This is a very readable online book on networking and sockets: http://beej.us/guide/bgnet/output/html/multipage/index.html

Talk about understanding the sockets API ;-) here's the content section for chapter 5:

  5.1. getaddrinfo() — Prepare to launch!
  5.2. socket() — Get the File Descriptor!
  5.3. bind() — What port am I on?
  5.4. connect() — Hey, you!
  5.5. listen() — Will somebody please call me?

I love beej's guide! Its where I learned socket programming. It is an art to make such a dry subject as entertaining as he does.
