🗣️ About

The aim of this project is to code a C library recoding usual functions that you'll be allowed to use in all your other projects.

For detailed information and comments, refer to the subject of this project.

🚀 TLDR: this project consists of coding basic C functions (see below), which are then compiled
into a library for use in other projects of the cursus.

Mandatory Part

Functions from <ctype.h> library

• ft_isalpha - alphabetic character test.
• ft_isdigit - decimal-digit character test.
• ft_isalnum - alphanumeric character test.
• ft_isascii - test for ASCII character.
• ft_isprint - printing character test (space character inclusive).
• ft_toupper - lower case to upper case letter conversion.
• ft_tolower - upper case to lower case letter conversion.

Functions from <stdlib.h> library

• ft_atoi - convert ASCII string to integer.
• ft_calloc - memory allocation (with malloc).

Functions from <strings.h> library

• ft_bzero - write zeroes to a byte string.

Functions from <string.h> library

• ft_strlen - find length of string.
• ft_memset - write a byte to a byte string.
• ft_memcpy - copy memory area.
• ft_memmove - copy byte string.
• ft_strlcpy - size-bounded string copying.
• ft_strlcat - size-bounded string concatenation.
• ft_strchr - locate character in string (first occurrence).
• ft_strrchr - locate character in string (last occurence).
• ft_strncmp - compare strings (size-bounded).
• ft_memchr - locate byte in byte string.
• ft_memcmp - compare byte string.
• ft_strnstr - locate a substring in a string (size-bounded).
• ft_strdup - save a copy of a string (with malloc).

Non-standard functions

• ft_substr - save substring from string (with malloc).
• ft_strjoin - concatenate two strings into a new string (with malloc).
• ft_strtrim - trim beginning and end of string with the specified characters with malloc).
• ft_split - split string, with specified character as delimiter, into an array of strings.
• ft_itoa - convert integer to ASCII string.
• ft_strmapi - create new string from modifying string with specified function.
• ft_striteri - modifies string with specific function.
• ft_putchar_fd - output a character to given file.
• ft_putstr_fd - output string to given file.
• ft_putendl_fd - output string to given file with newline.
• ft_putnbr_fd - output integer to given file.

Bonus part

Linked list functions

• ft_lstnew - create a new list (with malloc).
• ft_lstadd_front - add new element at the beginning of the list.
• ft_lstsize - count the elements in a list.
• ft_lstlast - find the last element of the list.
• ft_lstadd_back - add new element at end of the list.
• ft_lstdelone - delete element from the list.
• ft_lstclear - delete a sequence of elements of the list from a starting element.
• ft_lstiter - apply function to all the elements of the list.
• ft_lstmap - apply function to all the elements of the list and create a new list (with malloc).

🛠️ Testing

Makefile and re-link

Mandatory part

git clone https://github.com/pvaladares/42cursus-00-Libft.git && cd 42cursus-00-Libft && make

Typing again make should show the following message:

make: `libft.a' is up to date.

Mandatory part + bonus

make bonus

Typing again make bonus should show the following message:

make[1]: `libft.a' is up to date.
