Libft

Description

The Libft project involves creating a C library that contains standard C library functions (libc) along with other utility functions. This library will serve as a foundational tool for your future C programming projects at school. It includes functions for string manipulation, memory handling, and linked list management.

Project Objectives

• Reimplement a set of standard C library functions.
• Develop additional utility functions that are not available in libc.
• Learn dynamic memory management in C.
• Understand and utilize linked list structures.
• Create a reusable library for future projects.

Content

• Part 1 - Libc Functions:

  • Implementation of functions like ft_strlen, ft_memset, ft_strchr, etc., which mimic the behavior of standard libc functions.

• Part 2 - Additional Functions:

  • Utility functions such as ft_substr, ft_strjoin, ft_split, which are either not available in libc or exist in a different form.

• Bonus Part:

  • Linked list management functions like ft_lstnew, ft_lstadd_front, ft_lstsize, etc.

Compilation

1. Compile the library:

   make

2. Clean object files:

   make clean

3. Remove all generated files, including the library:

   make fclean

4. Recompile everything from scratch:

   make re

5. Include bonus functions:

   make bonus

Usage

To use the library in your project, include the libft.h header file and compile your program with the libft.a library:

#include "libft.h"

int main(void) {
    // Example usage
    char *str = ft_strdup("Hello, Libft!");
    ft_putstr_fd(str, 1);
    free(str);
    return (0);
}

To compile a program using Libft:

gcc -Wall -Wextra -Werror -L[path_to_libft.a] -lft your_program.c -o your_program
