[wdmaudiodev] WDM Audio Subdevice registration and unregistration From: "Lee Laborczfalvi" <labor.lg@xxxxxxxxx> To: wdmaudiodev@xxxxxxxxxxxxx Date: Wed, 25 Jun 2008 16:57:34 +1000
I am working on modifying the MSVAD sample driver (simple) running on Windows Vista in order to allow the Wave and Topology subdevices to beregistered in response to an IOCTL sent from a user mode process. This isto provide dynamic subdevice creation functionality. I am also adding functionality to unregister the devices when a second IOCTL is received.
I'm doing something similar. I am writing a driver that was originally based on MSVAD multi. I want to add a new IOCTL to do some auxilliary processing. However, I can't figure out how to inform the port class of the handler routine for my new IOCTL. As far as I can see, all IOCTLs go to its dispatch routine and I never see them in my code.
Can you fill me in on how to do this?
