My very first C library
This project is about coding a C library. It contains a lot of general purpose functions my programs rely upon.. Version: 10.
Development repo for 42cursus libft project
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.
🚀 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.
-
ft_isalnum- alphanumeric character test. -
ft_isascii- test for ASCII character. -
ft_isalpha- alphabetic character test. -
ft_islower* - lower-case character test. -
ft_isupper* - upper-case 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_atoi- convert ASCII string to integer.
ft_calloc- memory allocation.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_strstr* - locate a substring in a string.ft_strnstr- locate a substring in a string (size-bounded).ft_strcmp* - compare strings.ft_strncmp* - compare strings (size-bounded).ft_strdup- save a copy of a string (with malloc).ft_strncat* - iterate and apply the func on every char.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_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_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.
Note: functions marked with * are bonus functions (not mandatory by the project's subject).
@tools
includes get_next_line and printf functions.
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 && make2. 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.h1. First, configure the path to the libft folder in the Makefile (inside /testing/):
#############################
## Path to Libft directory ##
#############################
DIR = ../2. Then run:
make
