Fab,
I have a few questions:
1) What's the right way to build the driver? Is there any document on
this?
I was able to use DDK to build latest code. But WDK 6001.18000 has
quite a lot of problems.
2) Is DDK build still supported? Our product is still under DDK.
Thanks,
James

What build environment are you using to run prefast? I didn't get these
errors when building with the latest WDK (6001.18001).

Hi,
I've made some modifications for the kernel mode driver to eliminate
Prefast errors. Can someone help to review the patch and check them in
if they're OK?
Patch file is also attached.
Thanks,
James
