Get Next Line

This project implements a function, get_next_line, that reads a single line from a file descriptor each time it is called, making it easy to handle line-by-line reading.

Features

• Reads from any file descriptor (e.g., files, standard input).
• Efficiently manages leftover data between calls.
• Utilizes a static buffer for minimal memory allocation and optimized performance.

Tests

Test with default buffer size

The default BUFFER_SIZE=42 and compiled with:

cc -Wall -Werror -Wextra ../get_next_line.c ../get_next_line_utils.c main.c -o main_test

Test with different buffer sizes

The tests cover:

BUFFER_SIZE=1

BUFFER_SIZE=0

BUFFER_SIZE=2048

BUFFER_SIZE=7

cd tests/
bash compile_tests.sh

Run

./main_test_default_buffer_42
./main_test_buffer_1
./main_test_buffer_0
./main_test_buffer_2048
./main_test_buffer_7

Assign your buffer size

Adjust -D BUFFER_SIZE=n where 'n' is the your buffer size'

cc -Wall -Werror -Wextra -D BUFFER_SIZE=n ../get_next_line.c ../get_next_line_utils.c main.c -o main_test_my_buffer_size

Test memory leaks

Replace 'your_program' with the name of your program.

valgrind --leak-check=yes ./your_program
