Subject: Problem: Curses on Sun 3/50

Help!

I have just received the `Towers of Hanoi' program which has been posted
to comp.sources...

The program runs on a VT100 without problems but on a Sun it produces strange
results. Apparently, the Sun window driver (or the tty emulator) buffers
characters to be output until there is a certain number of them, flushes them,
and then starts operating as one would expect. What I got actually was an
empty screen (after calling initscr), the program did something (it started
displaying characters which didn't reach my window), and then after a while I
got the expected pictures.

The time between initializing Curses and getting REAL output can be reduced by
just moving the window (but sending SIGWINCH doesn't work). Has anybody out
there in net.land made similar experiences with other programs using Curses on
the Sun?

It's not that I am particularly fond of Curses - I am just curious what kind
of bug this is (or maybe it's a feature, but I didn't find it documented :-).

Please respond by e-mail to ...!unido!iaoobel!wagner.

Thanx,
