Libft is a project at 42 that aims to recreate some of the standard C library functions and some additional ones that can be useful for later projects.
To use this library, you need to clone this repository and compile it with make. This will generate a libft.a file that you can link with your own source files.
The functions in this library are divided into three categories:
- Libc functions: These are functions that mimic the behavior of some of the standard C functions, such as
ft_memset,ft_bzero,ft_memcpy,ft_memcpy,ft_memmove,ft_memchr,ft_memcmp,ft_strlen,ft_strdup,ft_strlcpy,ft_strlcat,ft_strchr,ft_strrchr,ft_strnstr,ft_strncmp,ft_atoi,ft_isalpha,ft_isdigit,ft_isalnum,ft_isascii,ft_isprint,ft_toupper,ft_tolower andft_calloc. - Additional functions: These are functions that are not part of the standard C library, but are useful for some common tasks, such as
ft_substr,ft_strjoin,ft_strtrim,ft_split,ft_itoa,ft_strmapi,ft_putchar_fd,ft_putstr_fd,ft_putendl_fd andft_putnbr_fd. - Bonus functions: These are functions that deal with linked lists, such as
ft_lstnew,ft_lstadd_front,ft_lstsize,ft_lstlast,ft_lstadd_back,ft_lstdelone,ft_lstclear,ft_lstiter andft_lstmap.You can find more details about each function in the header filelibft.h.
To use this library in your own project, you need to include the header filelibft.h in your source files and link thelibft.a file when compiling. For example:
gcc -Wall -Wextra -Werror -I./libft -L./libft -lft main.c
