In following function code, ofs.close() results in failure to write last end tag of XML archive, apparently because stream is closed before destructor is executed, so when do we execute ofs.close() ? ofs.flush does not help either or shell we skip executing any flush or close and just return from function ?

template<class T>

void Serialize(const char * filename)

{

            std::ofstream ofs(filename);

            assert(ofs.good());

            boost::archive::xml_oarchive oa(ofs);     

            oa << BOOST_SERIALIZATION_NVP(T);

            ofs.close();

}
