<h3><a name="BOOST_PP_LIST_TO_TUPLE">#define BOOST_PP_LIST_TO_TUPLE</a>(LIST)</h3>
<p>Converts the list to a tuple.</p>
<p>For example,</p>
<pre>
<a href="list_to_tuple.htm#BOOST_PP_LIST_TO_TUPLE">BOOST_PP_LIST_TO_TUPLE</a>(<a href="tuple_to_list.htm#BOOST_PP_TUPLE_TO_LIST">BOOST_PP_TUPLE_TO_LIST</a>(3,(A,B,C)))
</pre>
<p>expands to <code>(A,B,C)</code>.</p>
<h3>Note</h3>
<ul>
<li>The supported size of the list being converted to a tuple is limited by
<a href="limits.htm#BOOST_PP_LIMIT_MAG">BOOST_PP_LIMIT_MAG</a> rather than <a href="limits.htm#BOOST_PP_LIMIT_TUPLE">BOOST_PP_LIMIT_TUPLE</a>.</li>
</ul>
<h3>Test</h3>
