I can see what you're trying to do. You're doing exactly the same thing
I've seen from embedded programmers just came to the great Linux world;
they often tend to call functions under #ifdef __KERNEL__. Don't do
that.

You should learn how to write a user application in linux environment.
i.e. You don't need {init,exit}_module, you don't define __KERNEL__ or
MODULE, you don't insmod to run your program. After that, the command
"man" should come in handy. e.g. man sendto, ...
