IDebugPendingBreakpoint2::EnumBoundBreakpoints

Enumerates all breakpoints bound from this pending breakpoint.

Syntax

int EnumBoundBreakpoints( 
   out IEnumDebugBoundBreakpoints2 ppEnum
);

Parameters

ppEnum
[out] Returns an IEnumDebugBoundBreakpoints2 object that enumerates the bound breakpoints.

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::EnumBoundBreakpoints(IEnumDebugBoundBreakpoints2** ppEnum)
{
   HRESULT hr;

   // Verify that the passed IEnumDebugBoundBreakpoints2 interface pointer
   // is valid.
   if (ppEnum)
   {
      *ppEnum = NULL;

      // Verify that the pending breakpoint has not been deleted. If
      // deleted, then return hr = E_BP_DELETED.
      if (m_state.state != PBPS_DELETED)
      {
         // If the bound breakpoint member variable is valid.
         if (m_pBoundBP)
         {
            // Get the bound breakpoint.
            CComPtr<IDebugBoundBreakpoint2> spBoundBP;
            hr = m_pBoundBP->QueryInterface(&spBoundBP);
            assert(hr == S_OK);
            if (hr == S_OK)
            {
               // Create the bound breakpoint enumerator.
               CComObject<CEnumDebugBoundBreakpoints>* pBoundEnum;
               hr = CComObject<CEnumDebugBoundBreakpoints>::CreateInstance(&pBoundEnum);
               assert(hr == S_OK);
               if (hr == S_OK)
               {
                  // Initialize the enumerator of bound breakpoints with
                  // the IDebugBoundBreakpoint2 information.
                  IDebugBoundBreakpoint2* rgBoundBP[] = { spBoundBP.p };
                  hr = pBoundEnum->Init(rgBoundBP, &(rgBoundBP[1]), NULL, AtlFlagCopy);
                  if (hr == S_OK)
                  {
                     // Verify that the passed IEnumDebugBoundBreakpoints2
                     // interface can be queried by the created
                     // CEnumDebugBoundBreakpoints object.
                     hr = pBoundEnum->QueryInterface(ppEnum);
                     assert(hr == S_OK);
                  }

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

   return hr;
}
