IDebugPendingBreakpoint2::EnumErrorBreakpoints

Mendapatkan daftar semua titik henti kesalahan yang dihasilkan dari titik henti yang tertunda ini.

Sintaks

C#

int EnumErrorBreakpoints( 
   enum_BP_ERROR_TYPE              bpErrorType,
   out IEnumDebugErrorBreakpoints2 ppEnum
);

C++

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

Parameter

bpErrorType
[di] Kombinasi nilai dari enumerasi BP_ERROR_TYPE yang memilih jenis kesalahan untuk dijumlahkan.

ppEnum
[out] Mengembalikan objek IEnumDebugErrorBreakpoints2 yang berisi daftar objek IDebugErrorBreakpoint2 .

Tampilkan Nilai

Jika berhasil, mengembalikan S_OK; jika tidak, mengembalikan kode galat. Mengembalikan E_BP_DELETED jika titik henti telah dihapus.

Contoh

Contoh berikut menunjukkan cara menerapkan metode ini untuk objek sederhana CPendingBreakpoint yang mengekspos antarmuka IDebugPendingBreakpoint2 .

HRESULT CPendingBreakpoint::EnumErrorBreakpoints(
   BP_ERROR_TYPE bpErrorType,
   IEnumDebugErrorBreakpoints2** ppEnum)
{
   HRESULT hr;

   // Verify that the passed IEnumDebugErrorBreakpoints2 interface pointer
   // is valid.
   if (ppEnum)
   {
      // Verify that the pending breakpoint has not been deleted. If
      // deleted, then return hr = E_BP_DELETED.
      if (m_state.state != PBPS_DELETED)
      {
         // Verify that this error is not a warning.
         // All errors supported by this DE are errors, not warnings.
         if (IsFlagSet(bpErrorType, BPET_TYPE_ERROR) && m_pErrorBP)
         {
            // Get the error breakpoint.
            CComPtr<IDebugErrorBreakpoint2> spErrorBP;
            hr = m_pErrorBP->QueryInterface(&spErrorBP);
            assert(hr == S_OK);
            if (hr == S_OK)
            {

               CComObject<CEnumDebugErrorBreakpoints>* pErrorEnum;
               hr = CComObject<CEnumDebugErrorBreakpoints>::CreateInstance(&pErrorEnum);

                  IDebugErrorBreakpoint2* rgpErrorBP[] = { spErrorBP.p };
                  hr = pErrorEnum->Init(rgpErrorBP, &(rgpErrorBP[1]), NULL, AtlFlagCopy);
                  if (hr == S_OK)

                     // interface can be queried by the created
                     // CEnumDebugErrorBreakpoints object.
                     hr = pErrorEnum->QueryInterface(ppEnum);
                     assert(hr == S_OK);
                  }

                  // Otherwise, delete the CEnumDebugErrorBreakpoints
                  // object.
                  if (FAILED(hr))
                  {
                     delete pErrorEnum;
                  }
               }
            }
         }
         else
         {
            hr = S_FALSE;
         }
      }
      else
      {
         hr = E_BP_DELETED;
      }
   }
   else
   {
      hr = E_INVALIDARG;
   }

   return hr;
