Libft

Table of Contents

Introduction

Libft is my personal implementation of some of the Standard C Library functions, along with additional utilities that I found necessary during my studies at 42. This project is intended to help me get a deeper understanding of data structures and basic algorithms by recreating fundamental C functions.

Contents

Libft is organized into several functional categories, each containing specific types of operations and utilities:

  • btree: (No specific functions listed yet)
  • ctype: Functions related to character classification and conversion (e.g., ft_isalpha, ft_toupper).
  • deque: Functions for handling double-ended queues (e.g., deque_push_right, deque_pop_left).
  • garbage_collector: Functions for memory management and custom allocation (e.g., ft_malloc).
  • hashtable: Functions for creating and managing hash tables.
  • list: Functions for linked list manipulation and operations (e.g., ft_lstnew, ft_lstadd_front).
  • math: (No specific functions listed yet)
  • stdio: Functions related to input/output operations, including a custom printf implementation.
  • stdlib: Standard library functions such as memory and string manipulation (e.g., ft_memset, ft_strdup).
  • string: Functions that deal with string operations and manipulations (e.g., ft_strtrim, ft_strjoin).

This organization helps in navigating the library and understanding the available functionalities that enhance standard C capabilities or provide additional useful tools.

Compilation

libft.a is the library file compiled from the source. To compile it, clone the repo and run make:

git clone https://github.com/your-username/libft.git
cd libft
make

This will compile all the functions into a single library file libft.a.

Usage

To use libft in your project:

  1. Include it in your C file: 
    #include "libft.h"
  2. When compiling your project, link against libft: 
    gcc -L. -lft your_c_file.c

Testing

For testing the library, you can use the Francinette or any other tester available.

Example Usage

Here is an example of using some of the libft functions:

#include "libft.h"

int main()
{
    ft_putstr("Hello, 42!");
    return (0);
}

This will print Hello, 42! using the ft_putstr function defined in libft.
