IoGetEeviceInterfaces

Hi there

Soory for my late response . I rechecked my use of IoGetDeviceInterfaces()
.
This api is used by me with NULL for PhysDeviceObject since I do not know
my DeviceObject inside
my miniport . I intend to get the whole list of interfaces (if more than
one ) and filter them.
The api is called from DriverEntry . Also I tried it from a woker thread .
In both cases I get a Bluse screen
with 0xc0000005 . Any explanation ? Or is there a way to know my
PhysDeviceObject inside my miniport to avoid the usage of NULL
as a non specified (optional) parameter ?

If you are discussing a scsi miniport driver, find the driver-object of your
miniport driver and you will get the PDOs of those scsi devices. But, the
PDO of the adapter is not there - it’s created by \Driver\PCI.
