Hello,
From DDK
“Callers of TdiBuildInternalDeviceControlIrp must be running at IRQL =
PASSIVE_LEVEL. Consequently, a client should preallocate a few IRPs with
this function so the client can use them to submit TDI_XXX requests when it
is running at a higher IRQL.”
TdiBuildInternalDeviceControlIrp requests FileObject as a parameter. How can
I prealocate IRP to send it down in TdiDispatchInternalDeviceControl
handler, which can run on IRQL DISPATCH_LEVEL, if I don’t have FileObject
yet?
Or maybe there is another way to create IRP and send it to the transport
from TdiDispatchInternalDeviceControl?
Thank you,
Leonid
Leonid,
Are you writing a client, or a TDI protocol driver?
If it is a client, pre allocate at the time of opening the connection.

Srin,
I am writing TDI filter, so I think I cannot sugest that my Dispatch handler
run below DISPATCH_LEVEL.

The wa I got around a problem like this was to allocate my own
IRP using IoAllocateIrp().
Remember though you need to clean up an irp you allocate this
way.

Just use the usual IoAllocateIrp to create an
MN_INTERNAL_DEVICE_CONTROL IRP. See the definition of
TdiBuildInternalDeviceControlIrp macro for details.
