| 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>. 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> | |
