Libft

This is my own standard library for C language! It is a first project of 42 and will be used in next projects. Every function is implemented in it own single file.

Functions

Funcion	Description
ft_atoi	Convert a string to int.
ft_itoa	Convert int to a new string.
ft_calloc	Alloc a array of nmemb elements with size bytes each.
ft_isalnum	Return if c is alfabetical or numeric.
ft_isalpha	Return if c is alfabetical.
ft_isascii	Return if c is ascii.
ft_isdigit	Return if c is digit.
ft_isprint	Return if c is printable.
ft_tolower	Convert a char to lower case.
ft_toupper	Convert a char to upper case.
ft_memset	Set byte c in first n bytes of a block memory.
ft_bzero	Set 0 in first n bytes of a memory block.
ft_memchr	Scans for c in first n bytes of a memory block, and return a pointer to it.
ft_memcpy	Copy first n bytes of src to dest. If overlap occours, the result is undefined.
ft_memmove	Copy first n bytes of src to dest. Treat ovarlap if it occours.
ft_memcmp	Compare first n bytes of two block memory.
ft_putchar_fd	Put char c in fd.
ft_putstr_fd	Put string in fd.
ft_putendl_fd	Put string in fd with new line character.
ft_putnbr_fd	Put number in fd.
ft_strlen	Return length of string *s.
ft_strchr	Return a pointer to first occurrence of c in string.
ft_strrchr	Return last occurrence of char c in string *s.
ft_strdup	Duplicate a string.
ft_strlcpy	Copy string *src to *dst.
ft_strlcat	Concatenate two strings *dst and *src.
ft_strjoin	Return a new string resulting of concatenation of *s1 and *s2.
ft_strncmp	Compare first n bytes of two strings *s1 and *s2.
ft_strnstr	Return a substring of a string.
ft_substr	Return new substring of string *s.
ft_strtrim	Return new string *s1 with it ends trimmed.
ft_split	Split string in array of words.
ft_striteri	Call a function f to every character in string *s.
ft_strmapi	Map every char of string *s to a new string.

Bonus functions

Function	Description
ft_lstnew	Create a new node.
ft_lstadd_front	Add a node at head of a list.
ft_lstadd_back	Add a node at tail of a list.
ft_lstsize	Return size of a list.
ft_lstlast	Return last node of a list.
ft_lstdelone	Delete one node.
ft_lstclear	Delete a node and their sucessors.
ft_lstiter	Call function f to every node in list.
ft_lstmap	Map every node of a list in a new list.

How to use

Follow these commands to compile the library:

git clone https://github.com/alissonmarcs/Libft.git
cd Libft
make bonus

Compiling with make bonus you will be able to use linked-list functions.

Supposing you have a main() defined in a main.c that call one of the functions above, compile it as follows:

cc main.c libft.a

Of course, include libft.h in your main.c.
