TDI Receive

NTDEV

I have some problems receiving data using TDI client.

Does anyone have good working examples. I prefere the method using

eventhandlers.

This is not reply but related question.

I have another big problem too but with TDI_EVENT_RECEIVE_DATAGRAM.

I have to return IRP for TDI_RECEIVE_DATAGRAM to TDI driver but my code’s
executing in DISPATCH level. Okay, I have pool of precreated IRPs and give
one from it. But where I can recreate new IRPs for this pool? Completion
routine is executing on DISPATCH level too. I think the right way is to
create new IRPs in separate thread but I hope there’s another way.

I can imagine only one possible solution. Do not receive fragmented UDP
datagrams.

IoAllocateIrp() is safe to call at dispatch level.

You might try setting *bytestaken = 0 to see if the TDI_RECEIVE_DATAGRAM
will then collect the entire datagram. - Eric

I think that you need a worker thread that watches your pool and creates
additional resources when they hit a “low-water” level.

Good luck,

Do not call TdiBuildInternalDeviceControlIrp, call
IoAllocateIrp+manual filling instead, you can do this on
DISPATCH_LEVEL.
