# get\_next\_line

This project is about programming a function that returns a line read from a file descriptor.

This project will not only allow you to add a very convenient function to your collection, but it will also make you learn a highly interesting new concept in C programming: **static variables.**

Before starting, we recommend you to watch the video below to better understand the subject. It's in french but you can add english subtitles.

*The video lasts 20 minutes but it will be the most worthwhile minutes of your life ;)*

Well, now that you have an overview of what we ask you to do, let's get started :)
