🗣️ About

The aim of this project is to make you code a function that returns a line ending with a newline, read from a file descriptor.

For detailed information, refer to the subject of this project.

🚀 TLDR: this project consists of coding a function that returns one line at a time from a text file.

@root

• 📁 get_next_line: source code developed for the project.
• 📁 testing: my own testing program.

Note: Files suffixed with _bonus are exact copies of corresponding files.

Functions in get_next_line.c

• ft_free_null - free and null a pointer.
• ft_cpy_exc_buff - copy read excess (string after \n) to static variable (buffer).
• ft_buff2line - copy read line from buffer.
• get_next_line - main function.

Functions in get_next_line_utils.c

• ft_strlen - find length of string.
• ft_strdup - save a copy of a string (with malloc).

🛠️ Usage

Requirements

The function is written in C language and thus needs the gcc compiler and some standard C libraries to run.

Instructions

1. Using it in your code

To use the function in your code, simply include its header:

#include "get_next_line.h"

and, when compiling your code, add the source files and the required flag:

get_next_line.c get_next_line_utils.c -D BUFFER_SIZE=<size>

If you're on Linux, you may as well need the following flags:

-D ARG_MAX="sysconf(_SC_ARG_MAX)" -D OPEN_MAX=1024

📋 Testing

1. Configuring

First, open the Makefile inside /testing/ and configure the path to the get_next_line folder:

GNL_FOLDER	= ../get_next_line

2. Running:

For basic testing, run:

make

For other tests, check all available rules in the Makefile.

make buf5000
