Re: minifilter context question

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

First consider asking this sort of question at http://www.osronline.com/ on
the NTFSD news group since that is where file system people hang out. A
STREAM_CONTEXT is a per file object context, and a STREAM_HANDLE context is
per handle. Never used FILE_CONTEXT since only Vista or later support it.

Does the FLT_FILE_CONTEXT and the FLT_STREAM_CONTEXT support context per
FILE_OBJECT (i.e. per process) or does it track this per FCB (across
processes) ?

So if process A and process B open a file foo.txt, I will see 2
irp_mj_create calls in my minifilter. If I want to track file_context,
will
I end up with 2 contexts (one for each process) or just one context with 2
reference counts ?

What is the difference between FLT_STREAM_CONTEXT and
FLT_STREAMHANDLE_CONTEXT?

Thanks
