KsDefaultDeviceIoCompletion function

The KsDefaultDeviceIoCompletion function is used to return a default response and to complete any device I/O control. It can be used in the KSDISPATCH_TABLE and as the default response to unknown Ioctl's. It is important to use this function so that queries such as property requests return the correct value rather than just STATUS_INVALID_DEVICE_REQUEST when properties are not support for instance.
