Gets a list of all error breakpoints that resulted from this pending breakpoint.

Syntax

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

int EnumErrorBreakpoints( 
   enum_BP_ERROR_TYPE              bpErrorType,
   out IEnumDebugErrorBreakpoints2 ppEnum
);

Parameters

bpErrorType
[in] A combination of values from the BP_ERROR_TYPE enumeration that selects the type of errors to enumerate.

ppEnum
[out] Returns an IEnumDebugErrorBreakpoints2 object that contains a list of IDebugErrorBreakpoint2 objects.

Return Value

If successful, returns S_OK; otherwise, returns an error code. Returns E_BP_DELETED if the breakpoint has been deleted.

Example

The following example shows how to implement this method for a simple CPendingBreakpoint object that exposes the IDebugPendingBreakpoint2 interface.

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)
            {
               // Create the error breakpoint enumerator.
               CComObject<CEnumDebugErrorBreakpoints>* pErrorEnum;
               hr = CComObject<CEnumDebugErrorBreakpoints>::CreateInstance(&pErrorEnum);
               assert(hr == S_OK);
               if (hr == S_OK)
               {
                  // Initialize the enumerator of error breakpoints with
                  // the IDebugErrorBreakpoint2 information.
                  IDebugErrorBreakpoint2* rgpErrorBP[] = { spErrorBP.p };
                  hr = pErrorEnum->Init(rgpErrorBP, &(rgpErrorBP[1]), NULL, AtlFlagCopy);
                  if (hr == S_OK)
                  {
                     // Verify that the passed IEnumDebugErrorBreakpoints2
                     // 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;
}
