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

I checked VC 7, header file for ofstream, destructor is empty, plus if we put this in multithread environment, it is necessary to ensure close() is executed before another thread attempts to access same file, unless xml_oarchive's destructor itself has a mechanism to close the stream once entire content is written to stream. _____ From: boost-users-bounces@lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of Robert Ramey Sent: Saturday, October 22, 2005 8:41 PM To: boost-users@lists.boost.org Subject: Re: [Boost-users] When to close ofstream in XML serialize Just remove the close(). This will permit the xml_archive destructor to be called while the stream is still open. The xml destructor adds some final tags to make a valid xml file.

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(); } _____ _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
