Is there any provision to add a FSCTL that a filter can use to interact with
an application program and a file it has opened.
i.e. The application program opens a file and then sends a unique FSCTL that
a filter driver would intercept, operate on the file and then return.

It is possible, but it is better to create a named control device object. Your current approach is likely to cause the interop issues.

I need the FileObject of the open file. I don’t see how a named control
object would allow this.
Thanks,

Pass file handle as IOCTL parameter.
Do ObReferenceObjectByHandle( *IoFileObjectType ) in the driver.

Now that I have the file object in my own device control. The other problem
is what device object (or instance in a Mini Filter) do I send the query to?
