title: Why was std::strstream deprecated?
body: <p>I recently discovered that <code>std::strstream</code> has been deprecated in favor of <code>std::stringstream</code>.  It's been a while since I've used it, but it did what I needed to do at the time, so was surprised to hear of its deprecation.</p>
  
  <p>My question is why was this decision made, and what benefits does <code>std::stringstream</code> provide that are absent from <code>std::strstream</code>?</p>
