Re: [Boost-users] When to close ofstream in XML serialize

You don't need the ofs.close() call. The destructor of std::ofstream
will take care of this.

What is T in your code? I think you need to pass an object in the
BOOST_SERIALIZATION_NVP macro. Take a look at the xml example in
demo_xml_save.cpp
