Partially asked in another question, but so far unanswered: Once I create a filtering_streambuf that is connected to the zlib_compressor() and the output file, how do I then construct an object that can accept data from the Stream Insertion Operator?

void CompressUsingFilteringStreambuf() { std::ofstream myFile("hello.z", std::ios_base::out | std::ios_base::binary);

boost::iostreams::filtering_streambufboost::iostreams::output out; out.push(boost::iostreams::zlib_compressor()); out.push(myFile);

// MY QUESTION: How can I use the "stream insertion" operator (<<) // to go through the filtering_streambuf // and place compressed text into myFile?

// HOW DO I CREATE someStream? someStream << "text I want to be compressed and end up in the Instead of someStream, try myFile, and see if the resulting hello.z is what you want. file...";

myFile.close(); }

I have scoured the documentation and the web looking for the answer -- and come up empty.
