Network Programming with Sockets
Beej 's Guide to Network Programming
Using Internet Sockets
Version 1.5.4 (17-May-1998)
[http://www.ecst.csuchico.edu/~beej/guide/net]
Intro
Hey! Socket programming got you down? Is this stuff just a little too difficult to figure out from the man pages? You want to do cool Internet programming, but you don 't have time to wade through a gob of structs trying to figure out if you have to call bind() before you connect(), etc., etc.
Well, guess what! I 've already done this nasty business, and I 'm dying to share the information with everyone! You 've come to the right place. This document should give the average competent C programmer the edge s/he needs to get a grip on this networking noise.
Audience
This document has been written as a tutorial, not a reference. It is probably at its best when read by individuals who are just starting out with socket programming and are looking for a foothold. It is certainly not the complete guide to sockets programming, by any means.
Hopefully, though, it 'll be just enough for those man pages to start making sense... :-)
Platform and Compiler
Most of the code contained within this document was compiled on a Linux PC using Gnu 's gcc compiler. It was also found to compile on HPUX using gcc. Note that every code snippet was not individually tested.
Contents:
What is a socket?
Two Types of Internet Sockets
Low level Nonsense and Network Theory structs--Know these, or aliens will destroy the planet!
Convert the Natives!
IP Addresses and How to Deal With Them socket()--Get the File Descriptor! bind()--What port am I on? connect()--Hey, you! listen()--Will somebody please call me?
