My implementation of some of the Standard C Library functions including some additional ones.
Libft is an individual project at 1337 from 42 network that requires us to re-create some standard C library functions including some additional ones that can be used later to build a library of useful functions for the rest of the program.
- Libc Functions: Some of the standard C functions
- Additional functions: Functions 42 deems will be useful for later projects
- Bonus Functions: Functions 42 deems will be useful for linked list manipulation
| Libc functions | Additional functions | Bonus Functions |
|---|---|---|
| memset | ft_memalloc | ft_lstnew |
| bzero | ft_memdel | ft_lstdelone |
| memcpy | ft_strnew | ft_lstdel |
| memccpy | ft_strdel | ft_lstadd |
| memmove | ft_strclr | ft_lstiter |
| memchr | ft_striter | ft_lstmap |
| memcmp | ft_striteri | |
| strlen | ft_strmap | |
| strdup | ft_strmapi | |
| strcpy | ft_strequ | |
| strncpy | ft_strnequ | |
| strcat | ft_strsub | |
| strlcat | ft_strjoin | |
| strchr | ft_strtrim | |
| strrchr | ft_strsplit | |
| strstr | ft_itoa | |
| strnstr | ft_putchar | |

Notes:
- Most of the the files and function names are namespaced with an ft in front. It stands for Fourty Two
- The project instructions require that we put all the source files in the root directory.
Bare in mind that my code is not the best ;).
The goal is to create a library called libft.a from the source files so I can later use that library from other projects at 1337 cursus.
To create that library, after downloading/cloning this project, cd into the project and call make:
git clone https://github.com/abdoabida/libft_abida.git
cd libft_abida
make
You should see a libft.a file and some object files (.o).
Now to clean up (removing the .o files), call make clean
I added a test file called test.c, it's using functions from the library to print the length of a string given as a parameter
If you try to compile it with gcc using gcc test.c you will get an undefined symbol error for the functions used.
You have to give the file the path of the library and which library it is using:
gcc test.c -L. -lft
-L takes the path to your library. . in this case
-l takes the name of your library. This is the set of characters that come after lib in your library name.
That's it. Now run it using ./a.out
Enjoy.
