screensaver question

[pjackson@rcsuna.gmr.com (Philip Jackson )]

I am developing an MCL application that does a lot of number crunching
for long periods of time. I would like to disable conventional screensavers
that compete for cpu cycles, so I am wondering if there is some relatively
easy way for my MCL application to programmatically blank out my entire
screen while it's running, then restore my entire screen when it's done..?

Of course, I suppose I can just turn off my tube, but that wouldn't be as
much fun as doing it via software...

Any help will be appreciated--
