Get Next Line (GNL)

Introduction

The get_next_line function is a project that is focused on static variables, file descriptors, and how to parse text data. The goal of this function is to read content from a file descriptor, line by line, until the end of the file.

Project Objective

The main objective of this project is to create a function that returns a line read from a file descriptor. The function should be memory leak-free and optimized for speed and efficiency.

Features

• Handles reading from file descriptors line by line.
• Efficient memory management to prevent leaks.

How to Use

Requirements

• A C compiler (I used cc)
• Make (optional for compilation automation)

Compilation

To compile the get_next_line library, run the following command:

cc -Wall -Wextra -Werror -D BUFFER_SIZE=42 get_next_line.c get_next_line_utils.c -o get_next_line

Note: Adjust BUFFER_SIZE according to your needs. It determines how much of the file is read at each call of read().

Integration

To use get_next_line in your project:

1. Include the header file in your source:

#include "get_next_line.h"

2. Compile your project along with get_next_line.c and get_next_line_utils.c.

3. Use the get_next_line function to read lines from a file descriptor:

int fd = open("your_file.txt", O_RDONLY);
char *line;

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