CBaseMediaFilter::GetSyncSource (Windows Embedded CE 6.0)

1/6/2010

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.

Requirements

Windows Embedded CE Windows CE 2.12 and later
Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
For more information, see Setting Up the Build Environment, Version 2.12 requires DXPAK 1.0 or later
