I've been trying out curses on an SGI Personal Iris. The problem
I can't figure out is; when I quit the program, the screen doesn't
get cleared. I get :
=====================================================
29
<blackjack \ hart >%(cursor here)
Hello, World! Using Curses!!
30
Hello, World! Using Curses!!
31
Hello, World! Using Curses!!
32
Hello, World! Using Curses!!
33
Hello, World! Using Curses!!
34
Hello, World! Using Curses!!
35
(etc.....)
======================================================
The prog is supposed to print Hello, World! Using Curses!!, then
a repetition count on the next line. (Needed the rep count, because
the PI was so fast, I couldn't tell if the thing running or not!).
Anyway, the prog quits with a ctl-C, and is supposed to clear the
screen. I've tried werase(stdscr), wclear(stdscr), and with & without
a wrefresh(stdscr). Am I being brain-dead, or is something funky
with curses on SGI?
=================prog below====================
