        var err = faceSDK.id3FacePortrait_GetExpression(_pHandle.value, pExpression);
        if (err != FaceError.success.value) {
          throw FaceException(err);
        }
        final vExpression = FaceExpressionX.fromValue(pExpression.value);
        return vExpression;

        calloc.free(pExpression);
      }
