IDebugBreakpointResolution2::GetResolutionInfo

 

如需 Visual Studio 2017 的最新文件請參閱 Visual Studio 2017 文件。

取得描述此中斷點的中斷點解析資訊。

語法

HRESULT GetResolutionInfo(   
   BPRESI_FIELDS       dwFields,  
   BP_RESOLUTION_INFO* pBPResolutionInfo  
);  

int GetResolutionInfo(   
   enum BPRESI_FIELDS   dwFields,  
   BP_RESOLUTION_INFO[] pBPResolutionInfo  
);  

參數

dwFields
[in]從旗標的組合BPRESI_FIELDS列舉型別，以決定哪些欄位的pBPResolutionInfo參數都必須填寫。

pBPResolutionInfo
[out]BP_RESOLUTION_INFO結構以填入此中斷點的相關資訊。

傳回值

如果成功，傳回S_OK; 否則會傳回錯誤碼。
