<p>An <a href="https://stackoverflow.com/questions/61278/quick-and-dirty-way-to-profile-your-code#231614">answer to one of my questions</a> included the following line of code:</p>

<pre><code>label = std::safe_string(name); // label is a std::string
</code></pre>

<p>The intent seems to be a wrapper around a string literal (so presumably no allocation takes place). I've never heard of <code>safe_string</code> and neither, apparently, has <a href="http://www.google.com/search?q=%22std%3A%3Asafe_string%22" rel="nofollow noreferrer">google</a> (nor could I find it in the 98 standard). </p>

<p>Does anyone know what this is about?</p>

There is no such thing as
```
std::safe_string
```
