Re: [Boost-users] [iostreams] How can I use the Stream Insertion operator (<<) with a filtering_streambuf?

This is how I do it with file_sink: boost::iostreams::filtering_ostream output_file; output_file.push(boost::iostreams::bzip2_compressor(boost::iostreams::bzip2_params(9))); output_file.push(boost::iostreams::file_sink("file.bz2", std::ios_base::binary)); output_file<<"blalba"; I think if you do just this, nothing happen until output_file is destroyed. So enclose in { }. Frédéric
