## Summary

> *The goal of this project is pretty straightforward. You will recode printf().

> You will mainly learn about using a variable number of arguments.*

> [Subject](https://cdn.intra.42.fr/pdf/pdf/58827/en.subject.pdf)

External functions: `write`, `va_start`, `va_arg`, `va_end`

Code written in accordance with **42 C** coding style,  **ANSI C89** compliant and entirely **documented with docstrings**.

## Usage

Compile the library with a simple `make -j` then add `#include "ft_printf.h"` to

your project and compile it with these additional flags:

    -I 

    -L 

    -l ftprintf

***Makefile rules***

- `make` -- compiles get_next_line.

- `make clean` -- deletes object files.

- `make fclean` -- deletes object files and get_next_line.

- `make re` -- fclean + make.

## Tester

- **[Printfest](test/printfest.c)** will try various, flags, value as well as

  undefined behavior cases to make sure that the program does not crash.

Usage: `cd test && make run`

## Tools

- **sanitizer**: `-fsanitize=address`

*Add `-g` flag when compiling with `-fsanitize=address` to print errors line numbers instead of addresses in hexadecimal.*
