HarmonyOS c++中使用SENSOR_TYPE_GYROSCOPE相关问题

参考这个用例改下：

g_user = OH_Sensor_CreateSubscriber();
int32_t ret = OH_SensorSubscriber_SetCallback(g_user, SensorDataCallbackImpl);
ASSERT_EQ(ret, SENSOR_SUCCESS);

Sensor_SubscriptionId *id = OH_Sensor_CreateSubscriptionId();
ret = OH_SensorSubscriptionId_SetType(id, SENSOR_ID);
ASSERT_EQ(ret, SENSOR_SUCCESS);

Sensor_SubscriptionAttribute *attr = OH_Sensor_CreateSubscriptionAttribute();
ret = OH_SensorSubscriptionAttribute_SetSamplingInterval(attr, SENSOR_SAMPLE_PERIOD);
ASSERT_EQ(ret, SENSOR_SUCCESS);

ret = OH_Sensor_Subscribe(id, attr, g_user);
ASSERT_EQ(ret, SENSOR_SUCCESS);

std::this_thread::sleep_for(std::chrono::milliseconds(SLEEP_TIME_MS));
ret = OH_Sensor_Unsubscribe(id, g_user);
ASSERT_EQ(ret, SENSOR_SUCCESS);
if (id != nullptr) {
  OH_Sensor_DestroySubscriptionId(id);
}
if (attr != nullptr) {
  OH_Sensor_DestroySubscriptionAttribute(attr);
}
if (g_user != nullptr) {
  OH_Sensor_DestroySubscriber(g_user);
  g_user = nullptr;
}

void SensorDataCallbackImpl(Sensor_Event *event)
{
  if (event == nullptr) {
    SEN_HILOGE("event is null");
    return;
  }
  int64_t timestamp = INVALID_VALUE;
  int32_t ret = OH_SensorEvent_GetTimestamp(event, &timestamp);
  ASSERT_EQ(ret, SENSOR_SUCCESS);
  Sensor_Type sensorType;
  ret = OH_SensorEvent_GetType(event, &sensorType);
  ASSERT_EQ(ret, SENSOR_SUCCESS);
  Sensor_Accuracy accuracy = SENSOR_ACCURACY_UNRELIABLE;
  ret = OH_SensorEvent_GetAccuracy(event, &accuracy);
  ASSERT_EQ(ret, SENSOR_SUCCESS);
  float *data = nullptr;
  uint32_t length = 0;
  ret = OH_SensorEvent_GetData(event, &data, &length);
  ASSERT_EQ(ret, SENSOR_SUCCESS);
  SEN_HILOGI("sensorType:%{public}d, dataLen:%{public}d, accuracy:%{public}d", sensorType, length, accuracy);
  for (uint32_t i = 0; i < length; ++i) {
  SEN_HILOGI("data[%{public}d]:%{public}f", i, data[i]);
}
}
