get_next_line

get_next_line is a function that reads a line from a file descriptor (like standard input, files, or sockets) and returns the line, including its newline character. The function is designed to handle large files and works without using libraries like getline.

📝 Overview

This project focuses on writing a function get_next_line that reads one line at a time from a file descriptor. The function should return a string (a line) when it’s called repeatedly. The function is useful for reading lines from a file or input stream one by one, instead of reading the entire file at once.

✨ Features

• Reads one line at a time from a file descriptor.
• Handles reading from files, stdin, and other sources.
• Efficient and optimized for handling large files or data streams.
• Does not use the getline function (i.e., you implement the line-reading behavior from scratch).

🚀 Getting Started

Prerequisites

• GCC or any C-compatible compiler
• make

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/get_next_line.git
   cd get_next_line

2. Compile the program:

    make
   

Testing the Function To test get_next_line, create a C file that includes get_next_line.h, call the function, and print the result to the console.

Example main.c:

#include "get_next_line.h"
#include <fcntl.h>
#include <stdio.h>

int main() {
    int fd = open("sample.txt", O_RDONLY);
    char *line;

    while ((line = get_next_line(fd)) != NULL) {
        printf("%s", line);
        free(line);
    }
    close(fd);
    return 0;
}

💡 Example of Usage: If you have a file sample.txt:

Hello, world!
This is a second line.
And this is the third.

After running the program with get_next_line, it will output:

Hello, world!
This is a second line.
And this is the third.

Each line will be printed separately as get_next_line returns one line at a time.
