get_next_line

Description

get_next_line is a function written in C that allows reading from a file descriptor line by line.

The main goal of this project is to gain a deep understanding of static variables, manage file reading operations, and develop proficiency in dynamic memory management (allocation/free). Although the standard C library provides functions like getline, this project focuses on reinventing the wheel to better grasp low-level I/O operations.

Instructions

File Structure

The project does not include a Makefile and consists of the following 3 main files:

• get_next_line.c: Contains the core logic of the function.
• get_next_line_utils.c: Includes helper functions (ft_strlen, ft_strjoin, etc.).
• get_next_line.h: Header file for the library.

---

Compilation

You can compile the project using gcc or cc by adding the BUFFER_SIZE flag. For example, to compile with a sample main.c:

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

Usage

The get_next_line function reads a single line from the given file descriptor (fd) and returns it as a dynamically allocated string.

Function Prototype:

char *get_next_line(int fd);

AI Usage

Artificial intelligence was used in this project for the following purposes:

• Writing and organizing the README file
• Ensuring functions comply with 42 norm rules
• Understanding the structure and behavior of the read function

The algorithmic design and implementation of the code were done by edpolat.
