how to process arrow, pageUp, pageDown keys in C or C++ on linux

How do I get the key codes so I can process arrow, pageUp, pageDown, etc, keys using simple C or C++?

I can get the regular keys, I do not know how to get these special keys.

Linux based systems follow the UNIX tradition, in the sense that those keys are special and their values depend on the terminal settings.

This is so, because in the old days each UNIX system had a complete different type of keyboard. As such it is somehow complex to be able to write generic code to handle those special keys.

The best way is to make use of a terminal handling library, like curses or its successor ncurses.

Here you can get a nice introduction about keyboard usage,

Ncurses should be able to handle that. There is lots of tutorials out there
