<div style="margin-left: 0px;"> The <b>BOOST_PP_TUPLE_TO_ARRAY</b>
macro
converts a <i>tuple</i> to an <i>array</i>. </div>
<h4> Usage </h4>
<div class="code"> <b>BOOST_PP_TUPLE_TO_ARRAY</b>(<i>size,tuple</i>)<br>
<br>
or<br>
<br>
<b>BOOST_PP_TUPLE_TO_ARRAY</b>(<i>...</i>) <a href="../topics/variadic_macros.html#VNotation" target="_self"><sup>(v)</sup></a><br>
</div>
<h4> Arguments </h4>
<dl>
<dt>size</dt>
<dd> The size of the <i>tuple</i>.&nbsp; Valid <i>tuple</i> sizes
range from <i>1</i> to <b>BOOST_PP_LIMIT_TUPLE</b>. <br>
</dd>
<dt>tuple</dt>
<dd> The <i>tuple</i> to be converted.</dd>
</dl>
<h4>Remarks</h4>
<div>
The <i>size</i> argument must be the actual size of the <i>tuple</i>.<br>
<br>
You can
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
