CBaseMediaFilter::GetSyncSource

The GetSyncSource method retrieves the reference clock that the object is using. This method implements the IMediaFilter::GetSyncSource method.

Syntax

  HRESULT GetSyncSource(
    IReferenceClock **pClock
);

Parameters

pClock

Address of a variable that receives a pointer to the clock's IReferenceClock interface.

Return Value

Returns S_OK or E_POINTER.

Remarks

If the object is not using a reference clock, *pClock is set to NULL. When the method returns, if *pClock is non-NULL, the IReferenceClock interface has an outstanding reference count. Be sure to release it when you are done.

Requirements

**  Header:** Declared in Amfilter.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
