libft

Description

Libft is the foundational project of the 42 curriculum. Its primary goal is to recreate a wide range of standard C library functions, providing a deep understanding of memory management, pointer arithmetic, and data structures.

Technical Details (Library Description)

The library is compiled into a single static library file libft.a. It consists of the following functional categories, all strictly adhering to the 42 Norm:

1. Libc Functions

Recreations of standard functions from <ctype.h>, <string.h>, and <stdlib.h>:

• ft_isalpha, ft_isdigit, ft_isalnum, ft_isascii, ft_isprint
• ft_strlen, ft_memset, ft_bzero, ft_memcpy, ft_memmove, ft_strlcpy, ft_strlcat
• ft_toupper, ft_tolower, ft_strchr, ft_strrchr, ft_strncmp, ft_memchr, ft_memcmp, ft_strnstr, ft_atoi
• ft_calloc, ft_strdup

2. Additional Functions

Non-standard utility functions for advanced string manipulation and memory allocation:

• ft_substr, ft_strjoin, ft_strtrim, ft_split, ft_itoa
• ft_strmapi, ft_striteri, ft_putchar_fd, ft_putstr_fd, ft_putendl_fd, ft_putnbr_fd

3. Linked List

A complete set of functions to manage singly linked lists. This is a core part of the library designed to handle dynamic collections of data.

• Structure Definition:

  typedef struct s_list
  {
      void            *content;
      struct s_list   *next;
  }   t_list;

Implemented Functions: ft_lstnew, ft_lstadd_front, ft_lstsize, ft_lstlast, ft_lstadd_back, ft_lstdelone, ft_lstclear, ft_lstiter, ft_lstmap.

Instructions

Compilation

The library is compiled using cc with -Wall -Wextra -Werror flags.

To compile the entire library (including linked list functions) and generate libft.a:

make : Compiles mandatory functions.

Cleaning Up
make clean: Removes all generated object files (.o).

make fclean: Removes all object files and the compiled libft.a library.

make re: Forces a complete recompilation from scratch (equivalent to make fclean && make).
