A custom C library that reimplements a set of standard functions from <libc>, developed as the first project of the 42 Cursus. Designed to provide fundamental functionality used across future projects.
This library includes:
- Character classification and conversion functions (
ft_isalpha,ft_toupper, etc.) - Memory manipulation (
ft_memcpy,ft_memset,ft_calloc, etc.) - String handling (
ft_strlen,ft_strjoin,ft_split, etc.) - I/O utilities (
ft_putchar_fd,ft_putendl_fd, etc.) - Linked list operations (
ft_lstnew,ft_lstadd_back,ft_lstmap, etc.)
These were implemented from scratch to replicate behavior in the C standard library.
- GCC (or compatible C compiler)
- Unix-like OS (Linux, macOS, WSL)
Clone the repository:
git clone https://github.com/hlntzg/Libft.git
cd Libft
Build the library:
make
This will generate libft.a.
To check which object (.o) files are inside libft.a:
ar -t libft.a
To clean object files:
make clean
make fclean # removes object files and libft.a
make re # rebuilds everything
Link libft.a into your C projects. Example:
gcc main.c -L/path/to/libft -lft -o my_program
