In a "low level" WDM driver, I would of course use IoRegisterDeviceInterface() to register the device interface. Thanks to the book that I have, I also know that it should be done *after creating* the device, but *before attaching* it to the device stack.
No wonder I am so confused... The book indeed instructs for calling IoRegisterDeviceInterface() *before attaching* the device object to the device stack. However, the WDK documentation says: "After creating the device object **and attaching it** to the device stack, one driver calls IoRegisterDeviceInterface..." Well, now at least I know that I can afford calling IoRegisterDeviceInterface() after calling PcAddAdapterDevice(). However, I am still confused about the role of IoRegisterDeviceInterface() in the world of PortCls. I tried to document my qualms in microsoft.public.development.device.drivers: http://tinyurl.com/yqeway Many thanks, Don ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/
