<p><b>Discussion:</b></p>
<p>The description of the meaning of the result of
<code>showmanyc()</code> seems to be rather strange: It uses calls to
<code>underflow()</code>. Using <code>underflow()</code> is strange because
this function only reads the current character but does not extract
it, <code>uflow()</code> would extract the current character. This should
be fixed to use <code>sbumpc()</code> instead.</p>


<p id="res-159"><b>Proposed resolution:</b></p>
<p>Change 31.6.3.5.3 <a href="https://wg21.link/streambuf.virt.get">[streambuf.virt.get]</a> paragraph 1,
<code>showmanyc()</code>returns clause, by replacing the word
&quot;supplied&quot; with the words &quot;extracted from the
stream&quot;.</p>
