📜 get_next_line

Custom implementation of a function that reads one line at a time from a file descriptor. Handles variable buffer sizes, maintains state across calls, and supports multiple file descriptors in the bonus version.

Build and run

# Clone
 git clone https://github.com/cmunoz-g/get_next_line.git
 cd get_next_line

Include in your project by adding:

• get_next_line.c
• get_next_line_utils.c
• get_next_line.h

Compile with a specified buffer size:

gcc -Wall -Werror -Wextra -D BUFFER_SIZE=42 main.c get_next_line.c get_next_line_utils.c -o my_program

Replace 42 with the buffer size you want.

Run your program:

./my_program

Features

• Line-by-line reading — returns each line including \n if present.
• Static state — keeps track of leftovers across multiple calls.
• Configurable buffer size — controlled at compile time with BUFFER_SIZE.
• Memory safety — manages dynamic memory to prevent leaks.

Project structure

• get_next_line.c — main line-reading logic.
• get_next_line_utils.c — helper functions.
• get_next_line.h — prototypes and includes.

Bonus

• Multiple file descriptors — supports parallel reads from multiple descriptors, storing state separately.
