The goal of this project is to re-code several functions from the Standard C library, along with additional supplementary functions, ensuring that they maintain the same behavior as the original ones.
C language |
Refactor certain functions from the Standard C library, ensuring that their behavior matches that of the original functions.

In order to utilize this "libft" library, you must initially clone the repository onto your local machine by employing a terminal:
- - $> git clone git@github.com:joaoneon/42_libft.git [folder]
| Command | Description |
| make all or make | compiles only the mandaory parts |
| make bonus | compiles the bonus part |
| make clean | deletes the object files created during compilation |
| make fclean | executes the clean command and also deletes the libft.a |
| make re | executes the fclean command followed by the all command |
| make rebonus | executes the fclean command followed by the bonus command |
Incorporate the header file of the "libft" library to utilize its functionalities in your projects:
- #include "libft.h"
When compiling your projects that utilize the "libft" library, it is necessary to employ the appropriate flags:
- $> ... -L [path/to/libft.a] -I [path/to/libft.h]
