get_next_line

📚 Project Overview

get_next_line is a 42 school project where the goal is to create a function that reads a file descriptor line by line, returning one line each time it’s called — just like reading a file with fgets(), but with custom memory management and buffer handling.

🔧 Function Prototype

char *get_next_line(int fd);
  • Returns the next line from a file descriptor
  • Includes the \n if present
  • Returns NULL on EOF or error
  • Bonus for multiple file descriptors included

✅ Requirements

  • No memory leaks
  • One line per call
  • Handle multiple file descriptors (bonus)
  • Norm compliant

🧪 Compilation Example

cc -Wall -Wextra -Werror get_next_line.c get_next_line_utils.c main.c
