The HW_STREAM_HEADER structure describes the kernel streaming semantics supported by the minidriver as a whole, as part of a HW_STREAM_DESCRIPTOR structure.
NumberOfStreamsThe number of HW_STREAM_INFORMATION structures that follow this header.
SizeOfHwStreamInformationThe size, in bytes, of the HW_STREAM_INFORMATION structure.
NumDevPropArrayEntriesThe number of entries in the array pointed to by DevicePropertiesArray.
DevicePropertiesArrayPointer to the beginning of the array of property sets that the minidriver as a whole supports. (Property sets supported by individual streams can be found in the StreamPropertiesArray member of the stream's HW_STREAM_INFORMATION structure.)
NumDevEventArrayEntriesThe number of entries in the array pointed to by DeviceEventsArray.
DeviceEventsArrayPointer to the beginning of the array of event sets supported by the minidriver.
TopologyPointer to the KSTOPOLOGY structure that describes the minidriver's internal topology of nodes and pins. The class driver uses this to handle the KSPROPSETID_Topology property set for the minidriver.
DeviceEventRoutinePoints to the minidriver's StrMiniEvent routine.
NumDevMethodArrayEntriesDeviceMethodsArrayReservedReserved for system use. Do not use.
