<h3 class="section">5.12 <code>memrchr</code>&mdash;reverse search for character in memory</h3>
<a name="index-memrchr"></a>
<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include &lt;string.h&gt;
void *memrchr(const void *<var>src</var>, int <var>c</var>, size_t <var>length</var>);

</pre></div>
<p><strong>Description</strong><br>
This function searches memory starting at <var>length</var> bytes
beyond <code>*<var>src</var></code> backwards for the character <var>c</var>.
The search only ends with the first occurrence of <var>c</var>; in
particular, <code>NUL</code> does not terminate the search.
</p>
<br>
<p><strong>Returns</strong><br>
If the character <var>c</var> is found within <var>length</var> characters
of <code>*<var>src</var></code>, a pointer to the character is returned. If
<var>c</var> is not found, then <code>NULL</code> is returned.
</p>
<br>
<p><strong>Portability</strong><br>
<code>memrchr</code> is a GNU extension.
</p>
<p><code>memrchr</code> requires no supporting OS subroutines.
</p>
<br>
