取得錯誤插入功能

注意

WHEA 錯誤插入介面需要具有 EINJ ACPI 資料表的電腦或實作 錯誤插入功能區域的PSHED Plug-In。 大部分的取用者系統不包含 EINJ 實作，而 Windows 沒有內建的 PSHED Plug-In來啟用錯誤插入。 當兩者都不存在時，錯誤插入介面會傳回錯誤。

使用者模式應用程式可以藉由呼叫 WHEAErrorInjectionMethods：：GetErrorInjectionCapabilitiesRtn 方法來取得硬體平臺錯誤插入功能的相關資訊。 這個方法會傳回 WHEA_ERROR_INJECTION_CAPABILITIES 結構，描述硬體平臺所支援的錯誤插入功能。

下列程式碼範例示範如何擷取錯誤插入功能資訊。

IWbemServices *pIWbemServices;
BSTR ClassName;
BSTR MethodName;
HRESULT Result;
IWbemClassObject *pOutParameters;
VARIANT Parameter;
ULONG Status;
WHEA_ERROR_INJECTION_CAPABILITIES ErrorInjectionCapabilities;

// The following example assumes that the application
// has previously connected to WMI on the local machine
// and that the pIWbemServices variable contains the
// pointer that was returned from the call to the
// IWbemLocator::ConnectServer method.

// Specify the class and method to execute
ClassName = SysAllocString(L"WHEAErrorInjectionMethods");
MethodName = SysAllocString(L"GetErrorInjectionCapabilitiesRtn");

// Call the GetErrorInjectionCapabilitiesRtn method indirectly
// by calling the IWbemServices::ExecMethod method.
Result =
  pIWbemServices->ExecMethod(
    ClassName,
    MethodName,
    0,
    NULL,
    NULL,
    &pOutParameters,
    NULL
    );

// Get the status from the output parameters object
Result =
  pOutParameters->Get(
    L"Status",
    0,
    &Parameter,
    NULL,
    NULL
    );
Status = Parameter.ulVal;
VariantClear(&Parameter);

// Get the capabilities from the output parameters object
Result =
  pOutParameters->Get(
    L"Capabilities",
    0,
    &Parameter,
    NULL,
    NULL
    );
ErrorInjectionCapabilities.AsULONG = Parameter.ulVal;
VariantClear(&Parameter);

// Process the error injection capabilities data
...

// Free up resources
SysFreeString(ClassName);
SysFreeString(MethodName);
pOutParameters->Release();
