Device Object pointer for filter driver

Hi,

  1. I want to use IOCalldriver to a function driver. Can someone help me how to do that ?
  2. How do I get the device object for the filter driver, which does not have a symbolic name.

Regards,
J. Joshua

Small modification to my question:

  1. I want to use IOCalldriver to a filter (either serenum.c or kbfiltr.c) driver. Can someone help me how to
    do that ?
  2. How do I get the device object for the filter driver, which does not have a
    symbolic name.

You should be calling either a driver below you if you are in the stack or
else call the top of the stack. See the long discussion on this list “How
to not allow attach to lower device” for information about how bad it is to
call into the middle of a stack. All I can say is you will be cursed by
many of us forever.

Why do you think you need this?
