Question Device driver Programming

I'm new to linux and just started my lessons on device Driver programming. I have few problems and i completely dont get the idea. Can anyone explai how to do this for the following code.

#include <linux/init.h>
#include <linux/module.h>
#include <linux/kernel.h>

static int hello_init(void)
printk(KERN_ALERT "Hello, world\n");
return 0;

static void hello_exit(void)
printk(KERN_ALERT "Goodbye, cruel world\n");

What exactly is your question? What don't you understand? Are you having problems building or loading the module?

Also, when posting code here, you should put it between [code] tags to preserve indentation and aid readability.

It's likely that the OP is already reading LDD3, though, since that example is from there.
