The minidriver uses the HW_STREAM_DESCRIPTOR structure to return stream information to the stream class driver.
Contains the HW_STREAM_HEADER for the stream descriptor.
Contains the HW_STREAM_INFORMATION block for the zero stream.
The minidriver returns this structure to the class driver in response to a SRB_GET_STREAM_INFO request. The class driver makes this request by calling the minidriver's StrMiniReceiveDevicePacket routine.
The class driver expects HW_STREAM_DESCRIPTOR to be laid out in memory as an HW_STREAM_HEADER followed by an array of HW_STREAM_INFORMATION structures. The array begins at the address of the StreamInfo member. The HW_STREAM_HEADER's NumberOfStreams member indicates the number of entries in the array. The minidriver uses HW_STREAM_HEADER to describe those kernel streaming properties of the driver as a whole, while each HW_STREAM_INFORMATION structure describes each individual stream the device supports.
