CBaseMediaFilter::GetSyncSource (Compact 2013)

3/26/2014

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.
