Re: [Boost-users] [Boost.Iostreams] does filtering_stream have a binary mode?

Hi,

Is there a way to set a filtering_stream to binary mode so I can use its operator>> and operator<< to read and write binary data?

Thanks.

I use ios_base::binary when I open the stream. Search the old newsgroup messages... there was some caution made about using << and >> with binary data. The recommendation was to use read and write instead. namespace io = boost::iostreams; io::filtering_ostream out; out.push(io::gzip_compressor()); out.push( io::file_sink("my_file.gz", ios_base::out | ios_base::binary)); NOW you can write to out
