- I just finished a device driver VXD for some non-linear video
- hardware we made. Under Win32s it uses "Universal Thunks" to thunk
- from a 32bit dll to a 16bit dll, at this point the 16 bit dll calls
- directly into the VXD. It's almost the same for Win95, but it uses
- "Flat Thunks" and a thunk compiler to create the thunk obj files.
- After MANY calls to Microsofts DDK support, and tons of docs, there
- is NO WAY to thunk and call a VXD under WinNT. Thunking don't exist
- in WinNT!
-
- If you could prove me wrong I'd be happy! Soon I might have to port
- the VXD code to WinNT. My understanding is I will have to do some
- reading on HAL ;-)
