About

This project is a C library of useful functions that are allowed to be used in future 42 School cursus projects. With access to this library, the coding process in incoming projects will be more effective. The aim of rewriting these functions is to get a better understanding of them, and get a wide range of utilities for the next projects.

The code in this repository follows the rules of the 42 Norminette.

Requirements

The library is written in C language and needs the gcc or clang compiler, with <stdlib.h> and <unistd.h> standard libraries to run.

Instructions

1. Compiling the library

For basic functions:

$ make

For bonus functions:

$ make bonus

2. Cleaning all binary (.o) and executable files (.a)

To delete all files generated with make, go to the path and run:

$ make fclean

3. Using it in your code

To use the library functions in your code, simply include this header:

#include "libft.h"

Testing

This library have been tested with Francinette.
