[Boost-users] convert a boost::iostreams::filter_streambuf to a std::wofstream

Hi: I'm trying to pass a boost::iostreams::filtering_streambuf to a boost::archive constructor. I'm using visual studio 2010, and am getting c2664 telling me that this conversion carn't be performed. Is there anyway I can convert a boost::iostreams::filtering_streambuf. Any help appreciated. Cheers Sean.
