[Boost-users] [asio] Passing streams into async_write()?

Hello, I have a std::istream that I pass into a function that calls async_write. Currently here is what I have: void SerialClient::DoWrite( std::istream const& data ) { boost::asio::async_write( m_port, boost::asio::buffer( data.rdbuf() ), boost::bind( &SerialClient::WriteCompleted, this, boost::asio::placeholders::error ) ); } Obviously this does not compile. There is no overload of buffer() that takes a streambuf. How can I get asio to write out my stream? --------- Robert Dailey
