[comp.sys.mac] Writing Stand Alone Tasks

milo@ndmath.UUCP (Greg Corson) (10/26/87)

I am trying to put together a special screen dimmer program for Mac and Mac II
computers.  I've got the installation part using an INIT 31 pretty well
figured out but with all the restrictions on using global variables & such
I am a little confused about a couple of things.

1. If you have a piece of stand alone code (say, triggered by the vertical
   interrupt manager) can you still use the window manager to put up a big
   window that overlaps the whole screen?

2. Can you still get at the font manager?

3. Can you still open and close disk files?

4. Is there any way to cause ALL the windows on screen (including the background)
   to go through an update event?

If anybody has answers to these questions I would appreciate it, particularly
if you have sample code that does any of the above things from a piece of
stand alone code (ie: not an application).
