IDebugPendingBreakpoint2::EnumBoundBreakpoints
Enumerates all breakpoints bound from this pending breakpoint.
Syntax
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;
}
