| 7 | <div style="margin-left: 0px;"> The <b>BOOST_PP_TUPLE_ENUM</b> macro converts a <i>tuple</i> to its comma-separated elements. The comma-separated elements are in the form of <i>variadic data</i>. </div> | |
| 8 | <h4> Usage </h4> | |
| 9 | <div class="code"> <b>BOOST_PP_TUPLE_ENUM</b>(<i>size,tuple</i>)<br> | |
| 10 | <br> | |
| 11 | or<br> | |
| 12 | <br> | |
| 13 | <b>BOOST_PP_TUPLE_ENUM</b>(<i>...</i>) <a href="../topics/variadic_macros.html#VNotation" target="_self"><sup>(v)</sup></a><b></b><br> | |
| 14 | </div> | |
| 15 | <h4> Arguments </h4> | |
| 16 | <dl> | |
| 17 | <dt>size</dt> | |
| 18 | <dd> | |
| 19 | The size of the <i>tuple</i>. | |
| 20 | Valid <i>tuple</i> sizes range from <i>1</i> to <b>BOOST_PP_LIMIT_TUPLE</b>. <br> | |
| 21 | </dd> | |
| 22 | <dt>tuple</dt> | |
| 23 | <dd> The <i>tuple</i> whose elements are to be converted. </dd> | |
| 24 | </dl> | |
| 25 | <h4> Remarks </h4> | |
| 26 | <div> | |
| 27 | <br>You can | |
| 28 | invoke the variadic version <a href="../topics/variadic_macros.html#VNotation" target="_self"><sup>(v)</sup></a> as BOOST_PP_TUPLE_ENUM(<i>tuple</i>) or | |
| 29 | BOOST_PP_TUPLE_ENUM(<i>size</i>,<i>tuple</i>).<br> | |
