C++ (Cpp) TransformFilter_Create Examples

Example #1

HRESULT ACMWrapper_create(IUnknown * pUnkOuter, LPVOID * ppv)
{
    HRESULT hr;
    ACMWrapperImpl* This;

    TRACE("(%p, %p)\n", pUnkOuter, ppv);

    hr = TransformFilter_Create(&(This->tf), &CLSID_ACMWrapper, &ACMWrapper_FuncsTable, NULL, NULL, NULL);

    if (FAILED(hr))
        return hr;

    *ppv = This;
    This->lasttime_real = This->lasttime_sent = -1;

    return hr;
}
