Create/Close on PDO ?

NTDEV
1

Hello,

What does it mean to get a Create/Close on a PDO ? Is it even possible ?

[Background: I am writing a driver which has the following 3
functionalities:

-Function Driver for Device A (which has its own hypothetical bus B, and
devices B1, B2 … on this bus).
-Bus Driver for hypothetical bus B.
-Function Driver for devices B1, B2, etc. on hypothetical Bus.]

My question is do I need to handle Create/Close for PDOs of B1, B2, etc. ?
When will I get such a request ?

I am really confused. Any help is appreciated!

Thanks
Puja

You know I was going to say that of course you have to support Create/Close,
as they will get called when somebody attaches above you, but on reflection
I don’t think that attaching a device object does anything other than modify
the target device AttachedDevices list. So I suppose the answer is that you
don’t have to support Create/Close. On the other hand, supporting these
routines is trivial.
