get_next_line

Objective

get_next_line is a function that reads a file descriptor line by line.
The goal of the project is to learn how to handle dynamic memory allocation, manage buffers, and efficiently read files in C.

---

Usage

To compile the project:

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

How it Works

get_next_line works by:

1. Reading from a file descriptor into a buffer of size BUFFER_SIZE.
2. Storing any leftover content for the next call.
3. Extracting and returning one line at a time, including the newline character.
4. Managing memory dynamically to handle any line length.

Recap

• Handling file descriptors and low-level I/O in C.
• Using buffers to read data efficiently.
• Managing dynamic memory allocation and freeing memory correctly.
• Handling edge cases such as empty files or very long lines.
• Strengthening understanding of C fundamentals and memory management.
