Libft

This project is about understanding the way these functions work, implementing and learning to use them. You will create your own library. It will be helpful since you will use it in your next C school assignments.

libc functions

Your functions will have the same prototypes and implement the same behaviors as the originals. They must comply with the way they are defined in their man. The only difference will be their names.

C types

• isalpha
• isdigit
• isalnum
• isascii
• isprint
• toupper
• tolower

Strings

• strlen
• strlcpy
• strlcat
• strchr
• strrchr
• strncmp
• strnstr
• strdup

Strings - Memory

• memset
• bzero
• memcpy
• memmove
• memchr
• memcmp

stdlib

• atoi
• calloc

Additional functions

In this second part, you must develop a set of functions that are either not in the libc, or that are part of it but in a different form.

put_functions

• ft_putchar_fd

  Outputs a character to the given file descriptor.

• ft_putstr_fd

  Outputs a string to the given file descriptor.

• ft_putnbr_fd

  Outputs an integer to the given file descriptor.

• ft_putendl_fd

  Outputs a string to the given file descriptor followed by a newline.

---

• substr

  Allocates with malloc and returns a substring from the given string.

• strjoin

  Allocates with malloc and returns a new string which is the result of the concatenation of two strings.

• strtrim

  Allocates with malloc and returns a copy of a string with the characters specified in 'set' removed from the beginning and the end of the string.

• split

  Allocates with malloc and returns an array of strings obtained by splitting a string using the character 'c' as a delimiter.

• itoa

  Allocates with malloc and returns a string representing the integer received as an argument (negative numbers handled).

• strmapi

  Applies the function ’f’ to each character of the string ’s’, and passing its index as first argument to create a new string malloc resulting from successive applications of ’f’.

• striteri

  Applies the function ’f’ on each character of the string passed as argument, passing its index as first argument. Each character is passed by address to ’f’ to be modified if necessary.

Lists

typedef struct	s_list
{
	void			*content;
 	struct s_list		*next;
}					t_list;

• lstnew

  Allocates with malloc and returns a new node.

• lstadd_front

  Adds a node to the beginning of a list.

• lstsize

  Counts the number of nodes in a list.

• lstlast

  Returns the last node of a list.

• lstadd_back

  Adds a node to the end of a list.

• lstdelone

  Frees the memory of a node's content using the 'del' function and frees the node.

• lstclear

  Deletes and frees the given node and every successor of that node, using the function 'del' and free.

• lstiter

  Iterates a list and applies a function on the content of each node.

• lstmap

  Iterates a list and applies a function on the content of each node. Creates a new list resulting of the successive applications of the function.
