IMasterClock interface

The IMasterClock interface provides Microsoft DirectMusic streams with access to the current reference time from the master clock. The DMus port driver implements this interface to support accurate timing in the IMXF and IAllocatorMXF interfaces that make up the MIDI-transport part of the filter graph. When calling a DMus miniport driver's IMiniportDMus::NewStream method, the DMus port driver passes an IMasterClock reference as a call parameter. The IMasterClock interface wraps the master clock, as described in Latency Clocks.
