c++返回数据失败

[JT2508832759]

定义了返回值类型为结构体的函数，之后进行返回，在测试时发现不能返回data，但是改成void能够运行到return data 之上，难道是我定义的返回值类型不对？但是编译时也没有报错啊？
SensorDataStruct* GetAccDataBatched()
{
size_t sensorCount = 0;
imuConsentGiven = CreateEvent(nullptr, true, false, nullptr);

HMODULE hrResearchMode = LoadLibraryA("ResearchModeAPI");
if (hrResearchMode)
{
typedef HRESULT(__cdecl* PFN_CREATEPROVIDER) (IResearchModeSensorDevice** ppSensorDevice);
PFN_CREATEPROVIDER pfnCreate = reinterpret_cast<PFN_CREATEPROVIDER>(GetProcAddress(hrResearchMode, "CreateResearchModeSensorDevice"));
if (pfnCreate)
{
hr = pfnCreate(&m_pSensorDevice);
}
else
{
hr = E_INVALIDARG;
}

}
m_pSensorDevice->QueryInterface(IID_PPV_ARGS(&m_pSensorDeviceConsent));
m_pSensorDeviceConsent->RequestIMUAccessAsync(ImuAccessOnComplete);

m_pSensorDevice->DisableEyeSelection();

m_pSensorDevice->GetSensorCount(&sensorCount);
m_sensorDescriptors.resize(sensorCount);

m_pSensorDevice->GetSensorDescriptors(m_sensorDescriptors.data(), m_sensorDescriptors.size(), &sensorCount);

for (auto& sensorDescriptor : m_sensorDescriptors)
{
if (sensorDescriptor.sensorType == IMU_ACCEL)
{
m_pSensorDevice->GetSensor(sensorDescriptor.sensorType, &m_pAcclSensor);
}
}
m_pAcclSensor->OpenStream();
m_pAcclSensor->GetNextBuffer(&pSensorFrame);
hr = pSensorFrame->QueryInterface(IID_PPV_ARGS(&m_pSensorAccelFrame));

// get the sensor Frame and next buffer
const AccelDataStruct* accelBuffer;
size_t BufferOutLength;
// read sensor values ...
hr = m_pSensorAccelFrame->GetCalibratedAccelarationSamples(&accelBuffer, &BufferOutLength);

//程序运行到了获取寄存器中的数据和寄存器长度！！！！！

SensorDataStruct* data = new SensorDataStruct[BufferOutLength]; // ?
// … and copy them to return array
for (UINT i = 0; i < BufferOutLength; i++)
{
data[i].VinylHupTicks = accelBuffer[i].VinylHupTicks;
data[i].SocTicks = accelBuffer[i].SocTicks;
data[i].SensorValueX = accelBuffer[i].AccelValues[0];
data[i].SensorValueY = accelBuffer[i].AccelValues[1];
data[i].SensorValueZ = accelBuffer[i].AccelValues[2];
data[i].temperature = accelBuffer[i].temperature;
}

m_pSensorAccelFrame->Release();
return data;
}

取地址试试：

SensorDataStruct& GetAccDataBatched()//SensorDataStruct* GetAccDataBatched()

取地址试试：

SensorDataStruct& GetAccDataBatched()//SensorDataStruct* GetAccDataBatched()

这不是取地址，是返回引用
