Doubt in Setting Completion Routine!

Hi All,

In my file system filter driver, i tried to set the completion routine for a
Read Irp that comes from the IO Manager.

But, the control doesnot go to the Completion Routine at all.

But, in case, if i create a local irp(and send it down to read data) and
have a completion routine set, control go to Completion Routine.

Can Completion routine be set only for the irp that we created?

With Regards,
A.Ilamparithi.

It doesn’t matter who created the IRP - you always can set a completion
routine.
But if it is your driver that completes the IRP then the completion routine
which is set by this driver is not invoked.
