You should use a try/catch block to catch exceptions that occur in such circumstances, and/or check the status of any file access calls.

1. You should handle the exception. 2. You can write a method to check connection (through ping).

If you share which API you are using for file I/O then you'd get answer more accurately. Did you used std::fstream or some other API?
