Essentially you get to write a function like getstr.
I did this in
        http://invisible-island.net/dialog/dialog.html
(see inputstr.c - which is probably more complicated than you had in
mind since most of it is dealing with wide-characters... - but the
actual buffer management is not that complex).

dialog uses wtimeout rather than nodelay+napms
