C++ (Cpp) IAVIStream_ReadData Examples

Example #1

File: acmstream.c Project: WASSUM/longene_travel

static HRESULT WINAPI ACMStream_fnReadData(IAVIStream *iface, DWORD fcc,
					    LPVOID lp, LPLONG lpread)
{
  IAVIStreamImpl *This = (IAVIStreamImpl *)iface;

  TRACE("(%p,0x%08X,%p,%p)\n", iface, fcc, lp, lpread);

  assert(This->pStream != NULL);

  return IAVIStream_ReadData(This->pStream, fcc, lp, lpread);
}

Example #2

File: editstream.c Project: amaneureka/reactos

static HRESULT WINAPI IEditAVIStream_fnReadData(IAVIStream*iface,DWORD fcc,
                                                LPVOID lp,LONG *lpread)
{
  IAVIEditStreamImpl *This = impl_from_IAVIStream( iface );
  DWORD n;

  TRACE("(%p,0x%08X,%p,%p)\n",iface,fcc,lp,lpread);

  /* check parameters */
  if (lp == NULL || lpread == NULL)

  /* simply ask every stream and return the first block found */
  for (n = 0; n < This->nStreams; n++) {
    HRESULT hr = IAVIStream_ReadData(This->pStreams[n].pStream,fcc,lp,lpread);

    if (SUCCEEDED(hr))
      return hr;
  }

  *lpread = 0;
  return AVIERR_NODATA;
