取得此暫止中斷點所產生的所有錯誤中斷點的清單。

語法

HRESULT EnumErrorBreakpoints(   
   BP_ERROR_TYPE                 bpErrorType,  
   IEnumDebugErrorBreakpoints2** ppEnum  
);  

int EnumErrorBreakpoints(   
   enum_BP_ERROR_TYPE              bpErrorType,  
   out IEnumDebugErrorBreakpoints2 ppEnum  
);  

參數

bpErrorType
[in]從值的組合BP_ERROR_TYPE選取要列舉的錯誤類型的列舉型別。

ppEnum
[out]傳回IEnumDebugErrorBreakpoints2物件，其中包含一份IDebugErrorBreakpoint2物件。

傳回值

如果成功，傳回S_OK; 否則傳回錯誤碼。 傳回E_BP_DELETED若已刪除中斷點。

範例

下列範例示範如何實作這種簡單的方式CPendingBreakpoint公開物件IDebugPendingBreakpoint2介面。
