Classify network error from Microsoft OLE DB Provider for SQL Server E_FAIL(0x80004005) error

I'm using Microsoft OLE DB's C++ Template library to access SQL Server 2012 via the "Microsoft OLE DB Provider for SQL Server" provider.

I have ever encountered the following error:

[Error information returned from CDBErrorInfo::GetBasicErrorInfo()]

• HRESULT: 0x80004005
• Native Error: 11

[Error information returned from CComPtr::GetErrorInfo()]

• Error state: 1
• Severity: 16
• Source: Microsoft OLE DB Provider for SQL Server
• Error message: [DBNETLIB][ConnectionWrite(send()).]General network error. Check your network documentation.

And, My problem is:

1. Can I classify native error "11" directly as a network connection error, so that I can reconnect and retry again right away?
2. Where can I find the document or description about the native errors returned by the "Microsoft OLE DB Provider for SQL Server" providers? and see if there is any other case I need to retry again.
