[jira] [Created] (MESOS-4110) Implement `WindowsError` to correspond with `ErrnoError`.

-----------------------------------

             Summary: Implement `WindowsError` to correspond with `ErrnoError`.
                 Key: MESOS-4110
                 URL: https://issues.apache.org/jira/browse/MESOS-4110
             Project: Mesos
          Issue Type: Bug
          Components: stout
            Reporter: Alex Clemmer
            Assignee: Alex Clemmer


In the C standard library, `errno` records the last error on a thread. You can pretty-print it with `strerror`.

In Stout, we report these errors with `ErrnoError`.

The Windows API has something similar, called `GetLastError()`. The way to pretty-print this is hilariously unintuitive and terrible, so in this case it is actually very beneficial to wrap it with something similar to `ErrnoError`, maybe called `WindowsError`.
