💻 About

📚 This is my first project as a student at École 42. I have recoded some functions from the standard C library, as well as some other utility functions that I will use throughout my course.

⚠ This library is intended for use only for École 42 projects.

🎯 Briefing

Part	Functions
Libc Mandatory Functions	ft_memset, ft_bzero, ft_memcpy, ft_memccpy, ft_memmove, ft_memchr, ft_memcmp, ft_strlen, 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, ft_calloc, ft_strdup
Additional Mandatory Functions	ft_substr, ft_strjoin, ft_strtrim, ft_split, ft_itoa, ft_strmapi, ft_putchar_fd, ft_putstr_fd, ft_putendl_fd, ft_putnbr_fd
List Bonus Functions	ft_lstnew, ft_lstadd_front, ft_lstsize, ft_lstlast, ft_lstadd_back, ft_lstdelone, ft_lstclear, ft_lstiter, ft_lstmap

The behavior of libc functions is defined in man (3). The others are briefly mentioned below.

⚙ Features

String Functions

Function	Behavior
ft_substr	Allocates and returns a substring from the string `s`. The substring begins at index `start` and is of maximum size `len`.
ft_strjoin	Allocates and returns a new string, which is the result of the concatenation of `s1` and `s2`.
ft_strtrim	Allocates and returns a copy of `s1` with the characters specified in `set` removed from the beginning and the end of the string.
ft_split	Allocates and returns an array of strings obtained by splitting `s` using the character `c` as a delimiter. The array is ended by a NULL pointer.
ft_itoa	Allocates and returns a string representing the integer received as an argument.
ft_strmapi	Applies the function `f` to each character of the string `s` to create a new string resulting from successive applications of `f`.

File Writing Functions

Function	Behavior
ft_putchar_fd	Outputs the character `c` to the given file descriptor `fd`.
ft_putstr_fd	Outputs the string `s` to the given file descriptor `fd`.
ft_putendl_fd	Outputs the string `s` to the given file descriptor `fd`, followed by a newline.
ft_putnbr_fd	Outputs the integer `n` to the given file descriptor `fd`.

Linked List Functions

Function	Behavior
ft_lstnew	Allocates and returns a new list element. The variable `content` is initialized with the value of the parameter `content`. The variable `next` is initialized to NULL.
ft_lstadd_front	Adds the element `new` at the beginning of the list.
ft_lstadd_back	Adds the element `new` at the end of the list.
ft_lstsize	Counts the number of elements in a list.
ft_lstlast	Returns the last element of the list.
ft_lstdelone	Frees the memory of a list element, applying the function `del` to the content of the element.
ft_lstclear	Same as `ft_lstdelone` but for all elements starting in `lst`
ft_lstiter	Iterates the list `lst` and applies the function `f` to the content of each element.
ft_lstmap	Iterates the list `lst` and applies the function `f` to the content of each element. Creates a new list resulting of the successive applications of the function `f`. The `del` function is used to delete the content of an element if needed.

🚀 How it works

Clone this repository

git clone https://github.com/prmarquesz/libft.git

Running Makefile

Go to the directory where you cloned and run the command

make

Available Options

Command	Usage
`make`	Creates the library (equivalent to `make all` and `make libft.a`)
`make clean`	Removes the object files
`make fclean`	Removes the object files and the library
`make re`	Invokes `fclean` rule and then `all`
