Hi All,
         I have created multiple instances of my Filter Centric AVStream
driver by using a call KsCreateFilterFactory (), in which I give RefString
name which matches with "wave name" in INF, and  FilterDescriptor table,
which contains functions pointers related with Filter. Currently I am using
DispatchCreate and DispatchProcess.

What I want is, whenever any of Dispatch Routine related to that filter is
called, I want to know, which filter is responsible or associated with this

Lets say I have 2 filters name VAD1,VAD2 with wave name WAVE1,WAVE2. I want
to get either of these identifier from its DispatchRoutines to identify the
filter correctly.

Thanks and Regards,
