libft is a project designed to reimplement the functions of the C Standard Library (libc) and create your own custom standard library. In this project, you can improve your programming skills by rebuilding your basic functions in the C language on your own. In addition, you are also expected to implement some data structures such as linked lists and the functions related to these structures.
This project helps you to better understand the C language by creating on your own the basic functions needed when programming in C. It also gives you the opportunity to practice understanding data structures and building your own libraries.
ft_isalpha- checks for an alphabetic character.ft_isdigit- checks for a digit (0 through 9).ft_isalnum- checks for an alphanumeric character.ft_isascii- checks whether c fits into the ASCII character set.ft_isprint- checks for any printable character.ft_toupper- convert char to uppercase.ft_tolower- convert char to lowercase.
ft_memset- fill memory with a constant byte.ft_strlen- calculate the length of a string.ft_bzero- zero a byte string.ft_memcpy- copy memory area.ft_memmove- copy memory area.ft_strlcpy- copy string to an specific size.ft_strlcat- concatenate string to an specific size.ft_strchr- locate character in string.ft_strrchr- locate character in string.ft_strncmp- compare two strings.ft_memchr- scan memory for a character.ft_memcmp- compare memory areas.ft_strnstr- locate a substring in a string.ft_strdup- creates a dupplicate for the string passed as parameter.
ft_atoi- convert a string to an integer.ft_calloc- allocates memory and sets its bytes' values to 0.
ft_substr- returns a substring from a string.ft_strjoin- concatenates two strings.ft_strtrim- trims the beginning and end of string with specific set of chars.ft_split- splits a string using a char as parameter.ft_itoa- converts a number into a string.ft_strmapi- applies a function to each character of a string.ft_striteri- applies a function to each character of a string.ft_putchar_fd- output a char to a file descriptor.ft_putstr_fd- output a string to a file descriptor.ft_putendl_fd- output a string to a file descriptor, followed by a new line.ft_putnbr_fd- output a number to a file descriptor.
ft_lstnew- creates a new list element.ft_lstadd_front- adds an element at the beginning of a list.ft_lstsize- counts the number of elements in a list.ft_lstlast- returns the last element of the list.ft_lstadd_back- adds an element at the end of a list.ft_lstclear- deletes and free list.ft_lstiter- applies a function to each element of a list.ft_lstmap- applies a function to each element of a list.
