If you are a beginning programmer and you want to program a game with Wifi, you probably do not know how you to start out. Or if you quite simply do not desire to plunge into complicated network code, I've created a small library to make it simpler to do.
The library's functions create interfaces like Berkley sockets (functions with dswifi or under Linux), and also corrects small a bug in the current version of dswifi (in gethostbyname).
For instace, it incorporates two modules: TCP and HTTP. The TCP module makes it possible to communicate via TCP with a server or to simply create a TCP server on the DS. The HTTP module (not yet completed, nor documented, but usable: referer to the examples) creates a very simpe HTTP request (GET) in order to connect to a web page.
