Filter instances are file handles. The process that opened the file handle has 
access to it, but nothing else does. All access to the filter instance is via 
the file handle.

Subject: [wdmaudiodev] AVStream driver communication from user mode



Hi guys,

Is it possible to communicate with filter created via 'graphedit' from
user mode application?

'BindToObject' call seems to lead to creation of new filter instance,
but what I need is to communicate with existing filter instance.

Also, how to enumerate all the filter instances from user mode? Is
there any way how to distinguish them? (By id or something).
