IDrmPort2 interface (portcls.h)
The IDrmPort2 interface is used by a WaveCyclic or WavePci miniport driver to manage DRM-protected content (see Digital Rights Management). The port driver implements this interface and exposes it to the miniport driver. The WaveCyclic and WavePci port drivers support this interface. To determine whether a port driver supports the IDrmPort2 interface, a miniport driver calls the port (IPortWaveCyclic or IPortWavePci) object's QueryInterface method with REFIID IID_IDrmPort2. IDrmPort2 inherits from the IDrmPort interface.
The methods in this interface serve as alternate entry points to the DRM functions in the DRMK system driver, drmk.sys.
