How to detect that arrow key is pressed using C under Linux or Solaris?

Question

What is the best way to detect in a C program that arrow key is pressed under Linux or Solaris?

As I know there is no standard C function that can do it. I don't want to use int86 function. I need to do it in a portable way.

Edit: I am asking about console applications.

You should look at the curses/ncurses library which will give you advanced screen and keyboard handling for console applications.

There is a lot of documentation available for curses, which is an extensive library.

There is a write-up on this very question available here
