42 Yerevan Libft
For further information about 42cursus and its projects, please refer to 42cursus repo.
The aim of this project is to code a C library regrouping usual functions that you'll be allowed to use in all your other projects.
For detailed information, refer to the subject of this project.
๐ 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.
Note
Because of 42 School norm requirements:
- Each function can't have more than 25 lines of code.
- All variables are declared and aligned at the top of each function.
- Project should be created just with allowed functions otherwise it's cheating.
ft_isascii
- test for ASCII character.ft_isalnum
- alphanumeric character test.ft_isalpha
- alphabetic character test.ft_isdigit
- decimal-digit character test.ft_isprint
- printing character test (space character inclusive).ft_tolower
- upper case to lower case letter conversion.ft_toupper
- lower case to upper case letter conversion.
ft_bzero
- write zeroes to a byte string.ft_memset
- write a byte to a byte string.ft_memchr
- locate byte in byte string.ft_memcmp
- compare byte string.ft_memmove
- copy byte string.ft_memcpy
- copy memory area.
ft_strlen
- find length of string.ft_strchr
- locate character in string (first occurrence).ft_strrchr
- locate character in string (last occurence).ft_strnstr
- locate a substring in a string (size-bounded).ft_strncmp
- compare strings (size-bounded).ft_strdup
- save a copy of a string (with malloc).ft_strlcpy
- size-bounded string copying.ft_strlcat
- size-bounded string concatenation.
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.ft_itoa
- convert integer to ASCII string.ft_substr
- extract substring from string.ft_strtrim
- trim beginning and end of string with the specified characters.ft_strjoin
- concatenate two strings into a new string (with malloc).ft_split
- split string, with specified character as delimiter, into an array of strings.ft_strmapi
- create new string from modifying string with specified function.ft_striteri
- applies the specific function on each character of the string.
ft_lstnew
- create new list.ft_lstsize
- count elements of a list.ft_lstlast
- find last element of list.ft_lstadd_back
- add new element at end of list.ft_lstadd_front
- add new element at beginning of list.ft_lstdelone
- delete element from list.ft_lstclear
- delete sequence of elements of list from a starting point.ft_lstiter
- apply function to content of all list's elements.ft_lstmap
- apply function to content of all list's elements into new list.
The library is written in C language and thus needs the gcc compiler and some standard C libraries to run.
1. Compiling the library
To compile the library, run:
$ cd path/to/libft && make
2. Using it in your code
To use the library functions in your code, simply include its header:
#include "libft.h"
and, when compiling your code, add the required flags:
-lft -L path/to/libft.a -I path/to/libft.h
