##  Summary

First project of [42Paris](https://42.fr/) aims to create its own standard

library based on `libc` by creating certain existing and non-existing functions

from scratch.  This library is also intended to be used and enriched with the

functions of our choice throughout the curriculum.

> *"It will contain a lot of general purpose functions your programs will rely

> upon."* - [Subject](https://cdn.intra.42.fr/pdf/pdf/57361/en.subject.pdf)

> 

External functions: `malloc`, `free`, `write`

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



I chose not to protect the functions from NULL pointers passed to them as a

parameter, indeed I prefer to let an explicit `SEGV` happen rather than obscure

the problem behind a `return (NULL);` making it more tedious to debug from a

superior layer of abstraction.

This choice is also observable in the `libc`.  For example `STRLEN(3)`

implementation from `` will crash a program that tries to pass it a

`NULL` string instead of returning `NULL` as it would if it was protected.

##  Usage

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

your project and compile it with these additional flags:

    -I 

    -L 

    -l ft

***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

- **[libftTester](https://github.com/Tripouille/libftTester)**

- **[libft-unit-test](https://github.com/alelievr/libft-unit-test)**

## Tools

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

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