列舉所有來自此暫止中斷點繫結的中斷點。

語法

HRESULT EnumBoundBreakpoints(   
   IEnumDebugBoundBreakpoints2** ppEnum  
);  

int EnumBoundBreakpoints(   
   out IEnumDebugBoundBreakpoints2 ppEnum  
);  

參數

ppEnum
[out]傳回IEnumDebugBoundBreakpoints2列舉繫結的中斷點的物件。

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。
