return Size of the FIFO frame buffer, used for processing. throws DocumentException An error has occurred during Document Library execution.

## Implementation

    int getTemporalWindowSize() {
      Pointer<Int> pTemporalWindowSize = calloc();
      try {
        var err = documentSDK.id3DocumentAuthenticator_GetTemporalWindowSize(_pHandle.value, pTemporalWindowSize);
        if (err != DocumentError.success.value) {
          throw DocumentException(err);
        }
        final vTemporalWindowSize = pTemporalWindowSize.value;
        return vTemporalWindowSize;
      } finally {
        calloc.free(pTemporalWindowSize);
      }
    }
