42-libft

Overview

This project is a basic reimplementation of some essential glibc functions, without any special tricks.

libft is a first-year project from the 42 school, which I attended in 2013-2016. It abides to the strict rules of 42 not to exceed 5 functions per file, or 25 lines per function.

You can compile the project like this:

?> ./make

The code was written with macOS in mind but should work anywhere.
