System: ALTOS 1000 running Unix 5.3b (or so!) with Informix 2.10.03B

Hi,
	I have an application (Informix, actually) which uses curses (with the
MINICURSES option set), and I want to call a subroutine of my own from within
Informix which does *not* use curses.  So far, no problem; doing this is
fairly straightforward.

When my function returns control to the application I perform a call to
refresh() so that the screen is restored to the same state as before I trashed
it (are you with me so far?  Good!)...  Unfortunately, this doesn't work - as
far as I can see refresh() is too clever and only redraws the bits it "knows"
have been corrupted.

I experimented with clearok() and doupdate(), but these aren't included in
MINICURSES (at least, in the set of functions that Informix provide in their
library).  I even tried setting win->_clear = 1 and then calling refresh(),
but this didn't work!!  Before anyone suggests I try including the standard
curses library, this doesn't work either - it and the Informix libraries
conflict with some "identical" structures being different sizes!!

Is it possible to force the screen to be *completely* redrawn, and if so, how!?
If not, how about a method to get ^R into the keyboard buffer (if there is one
in raw mode under MINICURSES) so that the Application will redraw the screen
(like ^L in vi)...

Please reply via email; I'll summarize if enough interest is shown, etc.

			Chris
