Now i am returning the different error code(-2) if IP Helper Library function GetIfTable fails. I checked the all other call sites and we don't need to do any additional changes.

This looks much better to me. One question …

Looking at `createNetworkInterfaceXP` I wonder if its usage of
`enumAddresses_win` should clear the pending exception if
-2 is returned?
