IDebugBreakpointResolution2::GetResolutionInfo

  • 發行項

取得描述此斷點的斷點解析資訊。

語法

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

參數

dwFields
[in]來自BPRESI_FIELDS列舉的旗標組合，決定要填入參數的pBPResolutionInfo哪些字段。

pBPResolutionInfo
[out]要 填入此斷點相關信息的BP_RESOLUTION_INFO 結構。

傳回值

如果成功，則會傳回 S_OK；否則會傳回錯誤碼。

範例

下列範例會針對公開IDebugBreakpointResolution2 介面的簡單CDebugBreakpointResolution物件實作這個方法。

HRESULT CDebugBreakpointResolution::GetResolutionInfo(
   BPRESI_FIELDS dwFields,
   BP_RESOLUTION_INFO* pBPResolutionInfo)
{
   HRESULT hr;

   if (pBPResolutionInfo)
   {

      // member variable to the local BP_RESOLUTION_INFO variable.
      hr = CopyBP_RESOLUTION_INFO(m_bpResolutionInfo,
                                  *pBPResolutionInfo,
                                  dwFields);
   }
   else

   }

   return hr;
}

   HRESULT hr = S_OK;

   // Start with a raw copy.
   memcpy(&bpResDest, &bpResSrc, sizeof(BP_RESOLUTION_INFO));

   // The fields in the destination is the result of the AND of
   //  bpInfoSrc.dwFields and dwFields.
   bpResDest.dwFields = dwFields & bpResSrc.dwFields;

   // Fill in the bp location information if the BPRESI_BPRESLOCATION
   //  flag is set in BPRESI_FIELDS.
