get_next_line
A C function that reads any valid file line by line until the end.
get_next_line is a project at 42 that basically reads a file line by line. This project is frequently used in further projects.
What is it made for?
Disclaimer: There are so many easier methods of doing this by using standard C functions.
But the goal here is to be able to do it by using any functions from my libft and only the standard functions read, malloc and free.
I added a main file called main.c, it takes a file name as an argument, opens it and passes the file descriptor (fd) to get_next_line until get_next_line returns -1 or 0. Also I added main2.c, it takes two file names as an arguments, to show usage of multiple descriptors.
Note from subject:
get_next_line returns:
-1 an error has occurred0 the reading of whole file has been completed1 one line has been read
Download/clone this repo:
git clone https://github.com/AnneMedvedeva/get_next_line_42.git
Get into it and build the library:
cd get_next_line
make -C libft/
Build the executables:
gcc -Wall -Wextra -Werror -I./libft/includes/ -L./libft -lft -o gnl_1 get_next_line.c main.c
gcc -Wall -Wextra -Werror -I./libft/includes/ -L./libft -lft -o gnl_2 get_next_line.c main2.c
You can change main files at the end or write your own.
Usage:
./gnl_1 test_1.txt
./gnl_2 test_1.txt text_2.txt
