In trying to get input from the arrow keys via curses (ncurses) it won't catch as KEY_UP etc. I used the keypad function with a true argument but getch still returned an escaped sequence. How do I shift through the values returned by getch() and grab the arrow keys specifically?

I found the same problem on Mac OS X. But it was resolved by adding the following:

keypad(stdscr, TRUE);
