IMiniportWaveCyclic interface is the primary interface that is exposed by the miniport driver for a WaveCyclic audio device. The WaveCyclic port driver communicates with the miniport driver through this interface. The adapter driver creates the WaveCyclic miniport object and passes the object's
IMiniportWaveCyclic interface pointer to the WaveCyclic port driver's IPort::Init method (see the code example in Subdevice Creation).
IMiniportWaveCyclic inherits from the IMiniport interface.
An adapter driver forms a miniport/port driver pair by binding an
IMiniportWaveCyclic object to an IPortWaveCyclic object. The PortCls system driver registers this pair with the system as a wave filter.
IMiniportWaveCyclic interface provides a method for initializing the miniport object and a method for creating a miniport stream object. The stream object is associated with a pin on the WaveCyclic filter, which the adapter driver forms by binding the miniport object and the port object together.
The IMiniportWaveCyclic interface inherits from the IMiniport interface.
The IMiniportWaveCyclic interface has these methods.
|IMiniportWaveCyclic::Init||The Init method initializes the WaveCyclic miniport object. Initialization includes verification of the hardware using the resources specified in the resource list.|
|IMiniportWaveCyclic::NewStream||The NewStream method creates a new instance of a logical stream that is associated with a specified physical channel.|
