1. What is Libft?

This project is the implementation of Libc. There is a restriction of using library on carrying out the projects in 42. This is the first library that the Cadets can use.

2. How to archive as static library?

Libft is the static library. There is a Makefile which provides the common rules (all, clean, fclean, re) including bonus rule in the folder.

• For the Mandatory

make all

• For the Bonus

make bonus

3. Which are the allowed external functions?

1. write on <unistd.h>
2. malloc on <stdlib.h>
3. free on <stdlib.h>

4. What kind of functions in Libft?

5. How does every functions deal with the Undefiend Behaviors?

Every functions in Libft deals with Undefunded Behaviors as similar as How the Mac OS X does.

6. How to include the static library into the other project?

When you are compiling the project, type the command below appropriately.

gcc -Wall -Werror -Wextra -L <directory-name> -l <library-name>

The name of the static library should be started with lib and ends with .a. Also, <library-name> should be typed except lib and .a. When we set the static library name as libft.a, <library-name> should be ft.
