libft

A C library I built from scratch to replace the standard libc functions I wasn't allowed to use in school projects. Ended up using it in basically every subsequent C project. Every function is written by hand with a focus on getting the behavior exactly right.

What's in it

Character checks and conversion ft_isalpha, ft_isdigit, ft_isalnum, ft_isascii, ft_isprint, ft_toupper, ft_tolower

Memory ft_memset, ft_bzero, ft_memcpy, ft_memmove, ft_memchr, ft_memcmp, ft_calloc

Strings ft_strlen, ft_strlcpy, ft_strlcat, ft_strchr, ft_strrchr, ft_strncmp, ft_strnstr, ft_strdup, ft_substr, ft_strjoin, ft_strtrim, ft_split, ft_strmapi, ft_striteri

Conversion ft_atoi, ft_itoa

File descriptor output ft_putchar_fd, ft_putstr_fd, ft_putendl_fd, ft_putnbr_fd

Linked list bonus

Build and use

make        # compiles to libft.a
make bonus  # includes the linked list functions

#include "libft.h"

gcc your_file.c libft.a -o your_program
