42 Libtf - My first project in the 42 Core Curriculum

The first project of the 42 School aims to create a static library, whith simulates existents functions of native libraryes of C language. We'll need them in future projects in the school, to manipulate characters, strings, numbers and printing.

Use in your machine

1. Clone the repo

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

2. Get in the project folder

  cd libft

3. Compile the mandatory

  make

4. Compile the bonus files

  make bonus

4. Use it

MANDATORY

Check and manipulate characters:

Function	Description
ft_isalpha	Alphabetic character test.
ft_isdigit	Decimal-digit character test.
ft_isalnum	Alphanumeric character test.
ft_isascii	Test for ASCII character.
ft_toupper	Lower case to upper case letter conversion.
ft_tolower	Upper case to lower case letter conversion.

Manipulate strings:

Function	Description
ft_strlen	Find the length of the string.
ft_strlcpy	Size-bounded string copying.
ft_strlcat	Size-bounded string concatenation.
ft_strchr	Locate the character in the string (first occurrence).
ft_strrchr	Locate the character in the string (last occurrence).
ft_strncmp	Compare strings (size-bounded).
ft_strnstr	Locate a substring in a string (size-bounded)
ft_substr	Extract substring from a string.
ft_strjoin	Concatenate two strings into a new string (with malloc).
ft_strtrim	Trim the beginning and end of the string with the specified characters.
ft_split	Split string, with specified character as delimiter, into an array of strings.
ft_strmapi	Create a new string by modifying the string with a specified function.
ft_striteri	Iterates through a string, enabling character and index manipulation.

Manipulate memory:

Function	Description
ft_calloc	Memory allocation.
ft_memset	Write a byte to a byte string.
ft_bzero	Write zeroes to a byte string.
ft_memcpy	Copy memory area.
ft_memmove	Copy byte string.
ft_memchr	Locate byte in byte string.
ft_memcmp	Compare byte string.
ft_strdup	Save a copy of a string (with malloc).

Manipulate numbers:

Function	Description
ft_atoi	Convert the ASCII string to an integer.
ft_itoa	Convert integer to ASCII string.

Write to a file descriptor:

Function	Description
ft_putchar_fd	Output a character to the given file.
ft_putstr_fd	Output string to the given file.
ft_putendl_fd	Output string to given file with newline.
ft_putnbr_fd	Output integer to the given file.

BONUS

The bonus functios are optionals (as the name says), but they serve to get as ready to work with data structures, specificly linked lists.

Function	Description
ft_lstnew	Create new list.
ft_lstadd_front	Add a new element at the beginning of the list.
ft_lstadd_back	Add a new element at the end of the list.
ft_lstsize	Count elements of a list.
ft_lstlast	Find the last element of the list.
ft_lstdelone	Delete element from the list.
ft_lstclear	Delete the sequence of elements of the list from a starting point.
ft_lstiter	Apply function to the content of all list elements.
ft_lstmap	Apply function to the content of all list elements into a new list.
