Exception safety

[Sergey Gromov]

What happens if an extern(Windows) function throws?

Basically I want my export DLL interface functions to fail gracefully.
What happens if I don't catch?  Currently my typical export looks like
this, and it looks a bit verbose:

extern(Windows) export HRESULT DllRegisterServer()
{
  try
  {
    doStuff();
  }
  catch(Exception e)
  {
    myTrace("Shit happens. Reason: " ~ e.msg);
    return E_UNEXPECTED;
  }
  catch(Object obj)
  {
    myTrace("Shit happens. Reason: " ~ obj.toString());
    return E_UNEXPECTED;
  }
  catch
  {
    myTrace("Shit happens. Reason: unknown");
    return E_UNEXPECTED;
  }
  return S_OK;
}
