If aggregation is not required, the caller specifies this parameter as NULL. Pointer to the IUnknown interface of an object that needs to aggregate the stream object. This parameter points to a caller-allocated pointer variable into which the method writes a pointer to the stream object's IMiniportWavePciStream interface.
