C-std-library

This project recreates functions from the C standard library. It is implemented with only malloc, free, and write.

Usage

To use this library, follow these steps:

1. Create the library

• Clone or download the repository.
• In Mac OS, navigate to the local repository from the command line.
• Type the command "make re" into the command line and press return.
• This creates the libft.a library file which can be used to access the constituent functions.

2. Using the library in a C program

• One way to use this library is to copy the created libft.a file as well as the libft.h file into the directory which contains your C file which references the libft.a functions.
• In your C file, place the following line at the top:

3. To compile the file, link your program's .c file with the library object file in a command similar to the following:

#include "libft.h"

%gcc -o myprogram file.c -L./ -lft
