And if all I want is to read a raw character (no echo and no line editing),
then curses is not only overkill, but may not work.  What if I don't have a
termcap/terminfo entry?  The ioctl doesn't need it, but at least one version
of curses will silently exit(1) if it can't find one.  Also, I believe that
curses insists on having complete control over the terminal; you can't
reliably use stdio while curses is active.  Finally, endwin() always attempts
to move the cursor to the bottom of the screen, which is inappropriate.

(A background voice is heard: "Why don't you suggest something better, then?")
