## Implementation

    int getSmileThreshold() {
      Pointer<Int> pSmileThreshold = calloc();
      try {
        var err = faceSDK.id3FacePortraitProcessor_GetSmileThreshold(_pHandle.value, pSmileThreshold);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vSmileThreshold = pSmileThreshold.value;
        return vSmileThreshold;
      } finally {
        calloc.free(pSmileThreshold);
      }
    }
