📝 General

Library includes mainly a selection of replicated Libc functions.

It is complemented by additional, mostly string and print based functionality.

Bonus which is centered around linked lists is also integrated into the library.

ft_printf and gnl are combined to the project as well alongside other extra functions.

Project passes many of the 42 testers, including franzinette strict.

⚠️ Main branch is shared between other 42 projects and it is expanded from original subject. ⚠️

If you want to see the version used for school evaluation, check eval branch.

🛠️ Build

GNU make, gcc and ar are required to build, compile and archive the project.

git clone https://github.com/Jarnomer/libft.git

cd libft && make all

⚡ Usage

Build creates binary libft.a into root directory and it should be compiled with your project.

#include "./include/libft.h"

int main(void)
{
  char *str1 = "Hello ";
  char *str2 = "world!";
  char *result;

  result = ft_strjoin(str1, str2);
  ft_printf("Result: %s\n", result);
  ft_free_single(&result);
  return (0);
}

gcc main.c libft.a -o my_program

Here is an example how to implement libft into your Makefile.

$(NAME): $(OBJECTS)
  $(CC) $(CFLAGS) $^ $(LIBFTDIR)/$(LIBFTBIN) -o $@

$(OBJECTS): $(LIBFTDIR)/$(LIBFTBIN)

libft: $(LIBFTDIR)/$(LIBFTBIN)

$(LIBFTDIR)/$(LIBFTBIN): 
  @make -C $(LIBFTDIR) all

Each function is relying on each other when applicable.

char *ft_strjoin(char const *s1, char const *s2)
{
  char  *str;
  int    buffer_size;

  if (!s1 || !s2)
    return (NULL);
  buffer_size = ft_strlen(s1) + ft_strlen(s2) + 1;
  str = ft_calloc(buffer_size, sizeof(char));
  if (!str)
    return (NULL);
  ft_strlcat(str, s1, buffer_size);
  ft_strlcat(str, s2, buffer_size);
  return (str);
}

For my other 42 projects and general information, please refer the Hive42 page.

I have also created error handling unit testers for pipex, so_long and cub3D.

Cheers and good luck! 🥳
