No. There is no standard way AFAIK to do that. 
Standard says that all I/O functions (opening, closing, reading and
writing) are forwarded to the std::basic_filebuf class. Common
implementation of this class uses C file streams for all operations.
That is the case with Dinkumware, RW and stlport.

The only thing you can do is to implement your custom version of file
stream which would generaly mean you will need to create your version
of basic_filebuf class and new version of fstream class that uses that
new version of basic_filebuf for I/O.

In that implementation you will have to use CreateFile/CloseHandle and
other respective windows API functions.

As a starting point take a look at this article:
