View the official Windows Driver Kit DDI referenceNo description available.
The KsPinGetReferenceClockInterface function returns a COM style interface to the reference clock associated with Pin. This interface pointer will be an IKsReferenceClock interface.
Pin [in]A pointer to the KSPIN structure for which to return the reference clock interface.
Interface [out]A pointer to a memory location that receives the address of an IKsReferenceClock interface. This is a COM style interface with an associated reference count. Minidrivers must release the interface when finished with it.
KsPinGetReferenceClockInterface returns STATUS_SUCCESS and deposits the address of the IKsReferenceClock interface into Interface if the pin implements the clock or has received notification of the master clock through the KSPROPERTY_STREAM_MASTERCLOCK property. Returns STATUS_DEVICE_NOT_READY if the pin has not yet received notification of the master clock.
The most common time to call KsPinGetReferenceClockInterface is in a state transition to KSSTATE_ACQUIRE.
See AVStream Clocks for more information about using the IKsReferenceClock interface that this routine returns.
