STDAPI GetInterface(LPUNKNOWN pUnk, void **ppv)
{
    CheckPointer(ppv, E_POINTER);
    *ppv = pUnk;
    pUnk->AddRef();
    return NOERROR;
}

Example #2

File: ComObject.cpp Project: lemonxiao0/peerproject

LPUNKNOWN CComObject::GetInterface(REFIID pIID, BOOL bAddRef)
{
	LPUNKNOWN pInterface = CCmdTarget::GetInterface( &pIID );

	if ( ! pInterface && pIID == IID_IDispatch )
	{
		if ( POSITION pos = m_pDispatchMap.GetStartPosition() )
		{
			const IID* pDispIID;
			m_pDispatchMap.GetNextAssoc( pos, pInterface, pDispIID );
		}
	}

	if ( pInterface && bAddRef ) pInterface->AddRef();
	return pInterface;
}
