<div style="margin-left: 0px;"> The <b>BOOST_PP_LIST_TO_ARRAY</b> macro
converts a <i>list</i> to an <i>array</i>. </div>
<h4> Usage </h4>
<div class="code"> <b>BOOST_PP_LIST_TO_ARRAY</b>(<i>list</i>) </div>
<h4> Arguments </h4>
<dl>
<dt>list</dt>
<dd> The <i>list</i> to be converted. <br>
</dd>
</dl>
<h4>Remarks</h4>
<div> This macro uses <b>BOOST_PP_WHILE</b>. Within <b>BOOST_PP_WHILE</b>,
it is more efficient to use <b>BOOST_PP_LIST_TO_ARRAY_D</b>.<br>
<br>
If the <i>list</i> to be converted is empty, as represented by
'BOOST_PP_NIL', the resulting <i>array</i> is empty, as represented by '( 0, ()
)'.</div>
