Hello All,
I have been trying to implement Sink device that I would like to use
with boost::iostreams.

I have used Sink class example and now I am trying to use that as my
sink device for the stream object.

        char* file_name = "c:/devel/output/file_one.txt";

        typedef container_sink <std::iostream> some_sink;

        stream<some_sink, std::char_traits<char>> my_file_stream;

last line I get many errors as following:
