You need valid structures with the correct size.

You need GetDriverInfo or GetDriverInfo2 even if you only return
DDERR_UNSUPPORTED.

I just glanced at this but it looks okay.

Now I am passing in valid structures with valid stub functions.

I now implement GetDriverInfo but it's never called.

The behavior (from what I can tell) hasn't changed. DrvGetDirectDrawInfo is
called twice, then nothing. My driver is built for W2K - but I'm testing on
XP. The driver (being a W2K one) is built for DX7. My display driver is a
DX9 driver and I have DX9 installed. Could this cause my problems?
