   7 <div style="margin-left: 0px;"> The <b>BOOST_PP_TUPLE_TO_ARRAY</b>
   8 macro
   9 converts a <i>tuple</i> to an <i>array</i>. </div>
  10 <h4> Usage </h4>
  11 <div class="code"> <b>BOOST_PP_TUPLE_TO_ARRAY</b>(<i>size,tuple</i>)<br>
  12 <br>
  13 or<br>
  14 <br>
  15 <b>BOOST_PP_TUPLE_TO_ARRAY</b>(<i>...</i>) <a href="../topics/variadic_macros.html#VNotation" target="_self"><sup>(v)</sup></a><br>
  16 </div>
  17 <h4> Arguments </h4>
  18 <dl>
  19   <dt>size</dt>
  20   <dd> The size of the <i>tuple</i>.&nbsp; Valid <i>tuple</i> sizes
  21 range from <i>1</i> to <b>BOOST_PP_LIMIT_TUPLE</b>. <br>
  22   </dd>
  23   <dt>tuple</dt>
  24   <dd> The <i>tuple</i> to be converted.</dd>
  25 </dl>
  26 <h4>Remarks</h4>
  27 <div>
  28                         The <i>size</i> argument must be the actual size of the <i>tuple</i>.<br>
  29 <br>
  30 You can
  31 invoke the variadic version <a href="../topics/variadic_macros.html#VNotation" target="_self"><sup>(v)</sup></a> as BOOST_PP_TUPLE_TO_ARRAY(<i>tuple</i>) or
  32 BOOST_PP_TUPLE_TO_ARRAY(<i>size</i>,<i>tuple</i>).<a href="../headers/seq/to_array.html"></a>
