Libft

A library of standard C functions

This project is the first step of the 42 curriculum. It aims to implement your own standard C library and improve your knowledge of basic C (data types, memory). This library will be reused during the 42 cursus.

Functions

Category	Examples
Memory	memset, memcpy, bzero, calloc
Strings	strlen, strdup, strjoin, substr
Char	isalpha, isdigit, toupper
Convert	atoi, itoa
Linked list	lstnew, lstadd_back, lstsize

Installation

# Clone repo
git clone https://github.com/yannallo/libft.git

# Build library
make -C libft

Usage

At this point you should have a libft.a (Archive containing all the object file). You will need to include "libft.h" and link the library when compiling.

gcc -Ilibft main.c -Llibft -lft -o test

main.c

#include "libft.h"
#include <stdio.h>

int main(void)
{
  char  *s = ft_strdup("A simple string !!");

  printf("%s\n", s);
  free(s);
  return 0;
}
