Hi, I’m creating a minifilter that, for certain files, in the preread function I am filling in my own buffer and completeing the operation. I do all the checks for the file (extension, volume, etc.) in the create section so that it is only done once for each create, then I store it in a generic table (the files will be very few that i am looking at).
The problem is that I can’t figure out what to store in the table in the postcreate that I can then read out in the preread to match and say that this is one of the files I care about. ( RtlInsertElementGenericTable(&Table, ???, sizeof(???), &inserted); ).
Thank you in advance for any help!
This is what a context is for, you do not need a table. Look at “Managing
Contexts” under the IFS Design Guide. Using a generic table is really the
wrong idea here.

Thanks Don, I’m looking at that right now. Trying to get into the IFS paradigm from an NDIS background 
I think that FltMgr provides you the stream contexts exactly to avoid you
from maintaining any such tables yourself.
