mimicking the behavior of the get function, which reads a line from a file until a '\n' newline and returns it.

📖 get_next_line

Reading a line on a fd is way too tedious

💡 Mandatory Part

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,b 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.

Requirements

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

Instructions

1. 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

Simply run this command (change "xx" with desired buffer size) :

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

---

💡 Bonus Part

As a bonus to the Mandatory requirement, the function should manage multiple file descriptors at the same time.

For example, if you can read from the file descriptors 3, 4 and 5, you should be
able to read from a different fd per call without losing the reading thread of each
file descriptor or returning a line from another fd.
It means that you should be able to call get_next_line() to read from fd 3, then
fd 4, then 5, then once again 3, once again 4, and so forth...

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

#include "get_next_line_bonus.h"

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

get_next_line_bonus.c get_next_line_utils_bonus.c -D BUFFER_SIZE=<size>

📋 Testing

Simply run this command (change "xx" with desired buffer size) :

gcc -Wall -Werror -Wextra -D BUFFER_SIZE=xx get_next_line_bonus.c get_next_line_utils_bonus.c && ./a.out
