This project is about coding a C library. It will contain a lot of general purpose functions your programs will rely upon.

Implementation of original functions

• ft_isalpha checks for an alphabetic character
• ft_isdigit checks for an digit character
• ft_isalnum checks for an alphanumeric character
• ft_isascii checks for an ASCII character
• ft_isprint checks for an printable character
• ft_strlen calculate string length
• ft_memset fill memory
• ft_bzero set byte zero
• ft_memcpy memory area copy (not overlap)
• ft_memmove memory area copy (may overlap)
• ft_strlcpy string limited copy
• ft_strlcat string limited concatenation
• ft_toupper convert uppercase
• ft_tolower convert lowercase
• ft_strchr locate character in string (first occurrence)
• ft_strrchr locate character in string (last occurrence)
• ft_strncmp compare part of two strings
• ft_memchr locate character in memory (first occurrence)
• ft_memcmp compare memory areas
• ft_strnstr locate a substring in a string limited
• ft_atoi convert a string to an integer
• ft_calloc a memory allocator
• ft_strdup duplicate a string

Functions that are either not in the libc, or that are part of it but in a different form

• ft_substr create a substring
• ft_strjoin create a concatenated string
• ft_strtrim create a string trimmed
• ft_split split a string
• ft_itoa convert a integer to an string
• ft_strmapi create a new string applying a function
• ft_striteri apply a function to each string character
• ft_putchar_fd outputs the character
• ft_putstr_fd outputs the string
• ft_putendl_fd outputs the string followed by a newline
• ft_putnbr_fd outputs the integer

Functions that manipulating lists

• ft_lstnew create new node of list
• ft_lstadd_front adds the node to beginning of list
• ft_lstsize counts the number of nodes in a list
• ft_lstlast returns the last node of the list
• ft_lstadd_back adds the node to end of list
• ft_lstdelone frees node memory
• ft_lstclear frees list memory
• ft_lstiter applies the function on content of each node
• ft_lstmap creates a new list resulting of applying of the function
