Libft

Libft is a custom library of standard C functions developed as part of the 42 school curriculum. The goal of this project is to recreate common standard library functions, along with a few additional utilities, to better understand how these functions work internally and to practice writing efficient, reusable code.

Introduction

Libft is a foundational project in the 42 curriculum designed to help students build a better understanding of C programming, memory management, pointers, and data structures. The project involves implementing a set of standard functions (such as strlen, memset, and strjoin) and other utility functions that can be used in future projects.

Functions

Libft includes the following categories of functions:

1. Libc Functions: Reimplementations of standard C library functions.
2. Additional Functions: Utility functions not present in the standard C library.
3. Bonus: Functions for handling linked lists.

Some of the re-implemented functions include:

• ft_memset
• ft_bzero
• ft_memcpy
• ft_strlen
• ft_strchr
• ft_strdup
• ft_atoi
• ft_toupper
• ft_tolower

For a full list of functions, see the function list.

Usage

1. Clone the repository:

   git clone https://github.com/iaceene/libft.git

2. Navigate to the libft directory:

   cd libft

3. Compile the library:

   make

4. Include the compiled library (libft.a) in your C project:

   #include "libft.h"

Compilation

Libft is compiled using the provided Makefile. The following commands can be used to compile and manage the library:

• make: Compiles the library.
• make clean: Removes object files.
• make fclean: Removes object files and the library.
• make re: Recompiles the library from scratch.

Testing

You can test your libft implementation using external testers:

• libft-unit-test
• libft-war-machine
• libft-tester

Simply clone these repositories and run the tests.
