- Does anybody know of a way to read the back buffer in the same way as
- readdisplay() can read what is displayed on the screen? It must be
- possible since snoop (a demo program supplied by SGI) can do it.
-
- I've tried using fullscrn()/endfullscrn() and setting readsource
- appropriately, but I always end up reading the front buffer contents.
