Function reading line by line from a file descriptor

get_next_line

Goals : This project will not only allow you to add a very convenient function to your collection, but it will also allow you to learn a highly interesting new concept in C programming: static variables.

Calling your function get_next_line in a loop will then allow you to read the text available on the file descriptor one line at a time until the end of it.

Clone

Open a terminal and run following command:

git clone <repository url>

Run

Go to the created repository and then into the folders test. You can run the following command to test my project :

gcc -Wall -Wextra -Werror -D BUFFER_SIZE=1 ../get_next_line.c ../get_next_line_utils.c main.c  && ./a.out

Explanations

The read function uses the value of the BUFFER_SIZE variable, which is initialized at the compilation. Therefore, the flag -D BUFFER_SIZE=xx has to be used, otherwise its value by default is 42.

Feel free to modificate the value of the buffer or the file where it reads from.
