Libft42

This project is a C language library that includes over 40 utility functions, designed to enhance standard functionality. It features a Makefile that automates the compilation process, generating both a static (.a) and shared (.so) library for seamless integration into various projects.

• ft_memchr – Locates a byte in a memory block
• ft_memcmp – Compares memory blocks
• ft_memmove – Moves memory safely, even with overlapping regions
• ft_memset – Fills memory with a specified byte

String Manipulation

• ft_strcat – Concatenates two strings
• ft_strchr – Locates a character in a string
• ft_strcmp – Compares two strings
• ft_strdup – Duplicates a string

• ft_toupper – Converts a lowercase character to uppercase

Linked List Operations

• ft_lstadd_back – Adds a node at the end of a list
• ft_lstadd_front – Adds a node at the beginning of a list
• ft_lstclear – Clears an entire linked list
• ft_lstdelone – Deletes a single node from a list
• ft_lstiter – Iterates over a linked list and applies a function
• ft_lstlast – Retrieves the last node in a linked list
• ft_lstmap – Applies a function to each node and creates a new list
• ft_lstnew – Creates a new linked list node
• ft_lstsize – Counts the number of nodes in a list

File I/O Operations

• ft_putchar_fd – Writes a character to a file descriptor
• ft_putendl_fd – Writes a string followed by a newline to a file descriptor
• ft_putnbr_fd – Writes an integer to a file descriptor
• ft_putstr_fd – Writes a string to a file descriptor
• get_next_line – Reads a line from a file descriptor

Building the Library

Libft supports both static and shared library generation through the provided Makefile.

Generating a Static Library (libft.a)

To compile the static version of the library, run:

make

• Or

make static

Generating a Shared Library (libft.so)

To compile the static version of the library, run:

make shared 

Using the Library

To compile your program with libft, use one of the following methods:

- Direct Linking

cc -Wall -Wextra -Werror -Iinclude test.c libft.a -o foo 

• Or

- Using the Library Flag

cc -Wall -Wextra -Werror -Iinclude test.c -L. -lft -o foo

NOTE

• Replace test.c with your actual source file.

Cleanup

• To remove Object files, run:

make clean

• To remove libft.a, libft.so and object files, run:

make fclean
