Network socket programming (BSD sockets) is one of the dark arts, the point where legacy interfaces can become a real burden to the programmer. In this post I will propose some hints and techniques that might this a bit easier, provided your compiler is complying to C99. Since it seems that there has been some misunderstanding about this post: this is not a tutorial or introduction to socket programming. This is to show how C99 can help to deal with a badly designed legacy interface.
If you are interested in socket programming as such, you’d probably better look elsewhere. There is a lot of information available on the web. On the other hand if you don’t know much about sockets (of even nothing at all) you can just take this as an example of a type of interface with which you might be confronted when programming in C.
