# **get_next_line - 42 Network**  

## **Overview**  

Get Next Line delivers a function, `get_next_line()`, that retrieves a line from a file descriptor. It’s divided into two parts:

- **Mandatory Part**: A single function to read lines sequentially from a file descriptor or standard input.

- **Bonus Part**: Enhanced version supporting multiple file descriptors simultaneously with a single static variable.

### Key Features

- Returns a line ending with `\n` (unless EOF is reached without it).

- Handles both file input and standard input efficiently.

- Uses static variables for state persistence across calls.

- Bonus: manages multiple file descriptors without mixing their reading threads.

### Restrictions

- Written in C, adhering to the 42 Norm.

- No unexpected crashes (e.g., segmentation faults).

- No memory leaks from heap allocations.

- Compiled with `-Wall -Wextra -Werror` and `-D BUFFER_SIZE=n` (e.g., 42).

- No use of `libft`, `lseek()`, or global variables.

## Getting Started

### Prerequisites

- C compiler (e.g., `clang` or `gcc`).

- `make` utility.

### How to Build and Run

1. Clone the repository:

   ```bash

   git clone https://github.com/msabr/GET_NEXT_LINE_1337

   cd GET_NEXT_LINE_1337

2. Build the mandatory part:

   ```bash

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

3. Build the bonus part (optional, separately):

   ```bash

   cc -Wall -Wextra -Werror -D BUFFER_SIZE=42 get_next_line_bonus.c get_next_line_utils_bonus.c

4. Run with a file or standard input:

   ```bash

   ./a.out 

## Project Structure

- `get_next_line.c`: main function source.

- `get_next_line_utils.c`: helper functions.

- `get_next_line_bonus.h`: bonus function prototype.

- `get_next_line_bonus.c`: bonus main source.

- `get_next_line_utils_bonus.c`: bonus helper functions.
