libft

Development repository for the 42cursus Libft project @ 42 São Paulo

This project is your very first project as a student at 42. You will need to recode a few functions of the C standard library as well as some other utility functions that you will use during your whole cursus.

Usage

# create a main file.
$ make
$ gcc -L. -lft main.c
$ ./a.out

Example of main() file

#include "libft.h"

int	main(void)
{
	char *s;
	char *string = "hello world";
	int	size;

	size = ft_strlen(string);
	s = (char *)calloc(size + 1, sizeof(char));
	s = ft_memcpy((void*)s, (void*)s, size);
	ft_putstr(s);
	free(s);
	return (0);
}
