Get Next Line

Introduction

The Get Next Line project is a challenge to implement a function that reads a file descriptor line by line, handling variable buffer sizes and different file descriptors simultaneously. This project focuses on memory management, efficient reading, and handling edge cases, making it a fundamental exercise in low-level C programming.

Features

• Line-by-Line Reading:

  • Reads and returns the next line from a file descriptor, including the newline character \n.
  • Handles files with or without newline characters gracefully.

• Dynamic Buffer Size:

  • Works with any buffer size, defined at compile time using BUFFER_SIZE.

• Multiple File Descriptors (Bonus):

  • Supports reading from multiple file descriptors without losing context for any of them.

• Efficient Memory Management:

  • Uses a static variable to preserve data between calls, ensuring optimal memory usage and performance.
