Retrieves the current reference clock in use by this filter.
Syntax
HRESULT GetSyncSource(
IReferenceClock** pClock
);
Parameters
- pClock
Pointer to a reference clock; will be set to the IReferenceClock interface.
Return Value
Returns an HRESULT value
Remarks
This member function implements the IMediaFilter::GetSyncSource method.
It returns the value of m_pClock after adding a reference to it.
Be sure to release the interface by calling the IUnknown::Release method when finished with the pointer.
Filters should derive their filters from CBaseFilter and not from CBaseMediaFilter, so filters will not likely use this member function. Use CBaseFilter::GetSyncSource instead.
