Reading a line on a fd is way too tedious

💡 About the project

The aim of this project is to make you code a function that returns a line, read from a file descriptor.

You will understand how files are opened, read and closed in an OS,
and how they are interpreted by a programming language for further analysis.
This task is crucial to understand for a future programmer since much of the time is based
on manipulating files for data management and persistence.
This project consists of coding a function that returns one line at a time from a text file.

For more detailed information, look at the subject of this project.

🛠️ Usage

Requirements

The function is written in C language and thus needs the gcc compiler and some standard C libraries to run.

Instructions

1. Using it in your code

To use the function in your code, simply include its header:

#include "get_next_line.h"

and, when compiling your code, add the source files and the required flag:

get_next_line.c get_next_line_utils.c -D BUFFER_SIZE=<size>

📋 Testing

You can edit any of the text files or the main.c for further testing. If you are not specifying the BUFFER_SIZE in your terminal, the default value of BUFFER_SIZE will be set as 10. If you tempt to change the value of BUFFER_SIZE, simply run this command (change "xx" with desired buffer size, e.g. BUFFER_SIZE=9999) :

gcc -Wall -Werror -Wextra -D BUFFER_SIZE=xx get_next_line.c get_next_line_utils.c && ./a.out
