<p><b>Discussion:</b></p>
<p>
When issue <a href="lwg-defects.html#1445" title="Several iostreams member functions incorrectly specified (Status: Resolved)">1445</a><sup><a href="https://cplusplus.github.io/LWG/issue1445" title="Latest snapshot">(i)</a></sup> was resolved by adopting 
<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3168.htm">N3168</a>, it exposed the need to 
modify both overloads of <code>basic_istream::seekg</code> (by inserting "the function clears eofbit," after "except that"), 
but the fix applied to the text apparently forgets the second overload at 31.7.5.4 <a href="https://wg21.link/istream.unformatted">[istream.unformatted]</a> p43.
</p>

<p><i>[2013-10-17: Daniel provides concrete wording]</i></p>


<p>
It seems that the tiny sentence "SIMILARLY for 27.7.1.3/43 (<code>seekg</code>)." had been overlooked. I agree that the wording needs to be
applied here as well.
</p>

<p><i>[2015-05-06 Lenexa: Move to Ready]</i></p>

<p>MC: This was just missed when we added "the function first clears eofbit" to the other overload, Daniel agrees. Editing mistake.</p>
<p>Move to Ready, consensus.</p>



<p id="res-2244"><b>Proposed resolution:</b></p>
<p>This wording is relative to N3691.</p>

<ol>
<li><p>Change 31.7.5.4 <a href="https://wg21.link/istream.unformatted">[istream.unformatted]</a> p43 as indicated:</p>

<blockquote><pre>
basic_istream&lt;charT,traits&gt;&amp; seekg(off_type off, ios_base::seekdir dir);
</pre><blockquote>
<p>
-43- <i>Effects:</i> Behaves as an unformatted input function (as described in 27.7.2.3, paragraph 1), except
that <ins>the function first clears <code>eofbit</code>,</ins> it does not count the number of characters extracted<ins>,</ins> 
and does not affect the value returned by subsequent calls to <code>gcount()</code>. [&hellip;]
</p>
</blockquote></blockquote>
</li>
</ol>
