How about this: You have N buffers. You have tasks A and B, among others. When you switch from task A to task B you save the buffer mapping table along with the other stuff. Then when you switch back to A you check to make sure that the buffers have the same blocks in them. If they don't you write out the changed ones and read back in the ones that A is expecting. This is horrible if both A and B are making heavy use of the buffers but if A is using them heavily and B not very much then it isn't too bad. And it is compatible. Anyone see problems? -- Doug Collinge School of Music, University of Victoria, PO Box 1700, Victoria, B.C., Canada, V8W 2Y2 decvax!nrl-css!uvicctr!collinge decvax!uw-beaver!uvicctr!collinge ubc-vision!uvicctr!collinge
