取得中斷點錯誤解決方案資訊。

語法

HRESULT GetResolutionInfo(   
   BPERESI_FIELDS            dwFields,  
   BP_ERROR_RESOLUTION_INFO* pErrorResolutionInfo  
);  

int GetResolutionInfo(   
   enum_BPERESI_FIELDS        dwFields,  
   BP_ERROR_RESOLUTION_INFO[] pErrorResolutionInfo  
);  

參數

dwFields
[in]從旗標的組合BPERESI_FIELDS列舉型別，以決定哪些欄位的pErrorResolutionInfo要填寫。

pErrorResolutionInfo
[in、 out]BP_ERROR_RESOLUTION_INFO填入這些中斷點解決方式描述的結構。

傳回值

如果成功，傳回S_OK; 否則傳回錯誤碼。
