🗣️ 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.

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

📑 Index

@root

• 📁 get_next_line: source code developed for the project.

@/get_next_line/

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

Functions in get_next_line.c

• get_reminder - gets the reminder after the newline.
• check_newline - returns the index of the newline if found else returns -1.
• ft_strlen - find length of string.
• get_next_line - main function.

Functions in get_next_line_utils.c

• ft_strdup - save a copy of a string (with malloc).
• ft_calloc - allocates X size of memory and set it to 0.
• ft_strjoin - Joins 2 strings togather.

🛠️ 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

Notes

• static keyword
  • Making a global variable/function static: only visible within its own translation unit.
  • static (local variable): presistent across function calls and only visible within its function.

note: you cant use the same name for static variable and global static variable! but never do it.
