Implementing a system call for OpenBSD

TL;DR:
I found a printed copy of an assignment I had to do in 2005 back when I was a student to implement a system call for OpenBSD and Linux. I lost the original LaTeX file so I decided to rewrite it so I have a digital copy. The article originally covered loadable kernel modules (LKM) which is no longer a thing in OpenBSD, I trimmed that part. I also trimmed the Linux part because I didn’t care about it back then and did the minimum to pass ;-) This article is translated from French.

The content of this post is based on an assignment I wrote in 2005, back when I was a student at Epitech, so things have probably changed and this is by no means a tutorial: please don’t write system calls and don’t submit them to OpenBSD… unless you’ve been told it’s a good idea by OpenBSD developers.
