问题描述
我使用C ++中的下一个代码来使用WRL检索系统上的无线电设备
I use next code in C++ to retrieve the radio devices on the system using WRL
RoInitializeWrapper initialize(RO_INIT_MULTITHREADED);
ComPtr<IRadioStatics> radioFactory;
HStringReference classId(L"Windows.Devices.Radios.Radio");
HRESULT hres = RoGetActivationFactory(classId.Get(), __uuidof(IRadioStatics), &radioFactory);
ComPtr<IAsyncOperation<__FIVectorView_1_Windows__CDevices__CRadios__CRadio*>> asyncOperation;
hres = radioFactory->GetRadiosAsync(&asyncOperation);
asyncOperation->put_Completed
(
Callback<IAsyncOperationCompletedHandler< __FIVectorView_1_Windows__CDevices__CRadios__CRadio* >>
(
[](IAsyncOperation<__FIVectorView_1_Windows__CDevices__CRadios__CRadio* >* pHandler, AsyncStatus status)
{
// check status and use the stream here
return S_OK;
}
).Get()
);
ComPtr<__FIVectorView_1_Windows__CDevices__CRadios__CRadio> radios;
hres = asyncOperation->GetResults(&radios);
unsigned int num;
radios->get_Size(&num);
wprintf_s(L"Radio devices found: %u\n", num);编译为x64时它工作正常并返回找到的蓝牙无线电设备。
It works fine when compiled for x64 and returns my bluetooth radio device found.
但在x86中，此代码会导致下一个调试错误：
But in x86 this code causes next debug errors:

...并返回任何设备。
... and any device is returned.
我们将不胜感激任何帮助。
Any help will be appreciated.
