Overview

get_next_line is a basic C function, which each time run on the same file descriptor returns the next line until the file descriptor returns EOL. It comes handy when reading from a file of getting user input from stdin.

Requirements

All you need is a C compiler.

Build

Since this is just a simple function no build system required.

Usage

To use get_next_line include the src file to src list to your compilation process.

Example

main.c:

#include "get_next_line.h"

void main() {
    int fd = open("/etc/passwd", O_RDONLY);
    char *str = get_next_line(fd);
    printf("%s\n", str);
}

This is a example using the basic version of get_next_line.

gcc get_next_line.c get_next_line_utils.c main.c -D BUFFER_SIZE=<size> -o main

replace <size> with the number of bytes to be read each time a read system call is trigged.

Notes

• Using the standard version does not support reading from multiple file descriptor. To do so use the files ending with _bonus
• Returned buffers is up to used to memory manage.
