Could you write some tests for that? The behaviour is likely different between ddraw and d3d8/d3d9, so you need tests for all three. d3d10 Unmap() doesn't have a return code.
I think i should be able to write test for d3d8/d3d9 as I fiddled around with those tests it a bit before. I'll do later on this week.
As for ddraw, not sure i will be able to write test, never looked at it really (btw this app uses d3d8, not ddraw)
