Hi
I want to access another driver from my driver
I was searching a bit about this and couldn’t find how to do it
I want to access an av mini driver and I am also an av mini driver
how can I do this? any code references will really help
You can’t access a specific “driver” … you access a specific “device”, and that device is serviced by a driver.
Soooo… you open a WDF Target for the device that you want to send Requests to, and do a WdfRequestSend to that target.

By “av mini driver”, do you mean an AVStream driver? What kind of
information do you expect to exchange? Usually, an AVStream driver runs
quite independently. It controls its one piece of hardware, and it
provides services to one process. The streaming going on in process A
shouldn’t have any impact on process B.
