How do you get the remaining string after a string extracted from a sstream variable?
<p>Like I have a <code>stringstream</code> variable contains <code>"abc gg   rrr  ff"</code></p>

<p>When I use >> on that <code>stringstream</code> variable, it gives me <code>"abc"</code>. How can I get the remaining string: <code>" gg   rrr  ff"</code>? It seems neither <code>str()</code> nor <code>rdbuf()</code> does this work.</p>
