Libft

This is a library for C which recreates functions from libc and also adds some extra. This was a project from 42 Lisboa and was used for learning purposes.

How to install

This project uses a makefile to compile everything. To compile it run:

make

This compiles the core, functionality for lists and get_next_line. If you don't want lists or get_next_line you can run:

make [core|list|gnl]

If you have not added a module to your library file, you can add them by running the command above with the desired module.

Functions

Core:

The following functions work the same as in libc (without the ft_ prefix)

• 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_substr // Takes a string, start position and length. Then mallocs a new string with the contents from the original string

• ft_strjoin // Takes 2 strings, joins them together

• ft_strtrim // Takes 2 strings, removes characters show in second string from the start and end of the first string

• ft_split // takes a string and a character. Splits the string into an array of substrings where it is split on the char

• ft_itoa // Converts integer into a string

• ft_strmapi // Takes a string and a function (which takes the position in the string and a char) , applies the function to each character in a copy of the string

• ft_striteri // Takes a string and a function (which takes a char), applies the function to each char

• ft_putchar_fd // writes a char to a fd

• ft_putstr_fd // writes a string to a fd

• ft_putendl_fd // writes a string to a fd, and adds a newline

• ft_putnbr_fd // writes a number to a fd

Lists:

List is a struct with a (void * content), and a (t_list *next)

• ft_lstnew // Mallocs a ned node and takes content to initialize
• ft_lstadd_front // Adds a node the the start of the list
• ft_lstsize // Gets the length of the list
• ft_lstlast // Gets the last node of the list
• ft_lstadd_back // Adds a node to the end of a list
• ft_lstdelone // Takes a delete function and applies it to the content of a node and frees the memory of the node
• ft_lstclear // Deletes and frees every node of a list
• ft_lstiter // Iterates the list and applies a function to the content of each node
• ft_lstmap // Creates a copy of a list and applies a function to the content of each element

GNL:

gets next line in a file.

• get_next_line // Takes a fd and gets the next line
