title: Is it possible to pass a stringstream as a function parameter?
body: <p>Is it possible to pass in a stringstream and have the function write to it directly?</p>
  
  <p>I remember I saw a function invoked similar to something like this:</p>
  
  <pre><code>my_func(ss &lt;&lt; "text" &lt;&lt; hex &lt;&lt; 33);
  </code></pre>
