    <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>
