Using an inverted callback in a WDF driver

Gary_Little-3Gary_Little-3 Member Posts: 1,208
At first glance it appears that a synchronous queue in WDF, if not ideal, is
at least viable as an inverted call back in a WDF driver. Is this true, or
should I stick to a more classical method, such as cancel safe queues?

    You want to use a manual queue. If you want to store data when there are no pending requests, pair it with your own data queue/list.
