That's all for DDK. Will WDK support be checked in to trunk soon?

 

Thanks,

James

Subject: RE: [ofw] Prefast patch

 

Are there more lines that Prefast is not content with ?

Generally, i'd not like to add such changes in the transition period from DDK to WDK.

I'd postpone all the Prefast work till after that.

	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
