Hi, I would like to manage the compression & decompression of wide stream. I have already implemented this functionality for narrow stream by using Boost.Iostream, see the code snippet hereafter, but I'm really too newbie with this library to generalize with wide stream. Any and all help appreciated? <\code snippet> // Compression of narrow stream void compress(std::istream& is, std::ostream& os) { io::filtering_streambuf<io::output> out ; out.push(io::gzip_compressor()) ; out.push(os) ; io::copy(is, out) ; } // Decompression of narrow stream void decompress(std::istream& is, std::ostream& os) { io::filtering_streambuf<io::input> in ; in.push(io::gzip_decompressor()) ; in.push(is) ; io::copy(in, os) ; } <\code snippet> Marc Viala mviala@acticm.com
