| 8 | The <b>BOOST_PP_TUPLE_REM_CTOR</b> macro removes the parentheses from a <i>tuple</i>. | |
| 9 | </div> | |
| 10 | <h4>Usage</h4> | |
| 11 | <div class="code"> | |
| 12 | <b>BOOST_PP_TUPLE_REM_CTOR</b>(<i>size</i>, <i>tuple</i>)<br> | |
| 13 | <br> | |
| 14 | or<br> | |
| 15 | <br> | |
| 16 | <b>BOOST_PP_TUPLE_REM_CTOR</b>(<i>...</i>) <a href="../topics/variadic_macros.html#VNotation" target="_self"><sup>(v)</sup></a><br> | |
| 17 | </div> | |
| 18 | <h4>Arguments</h4> | |
| 19 | <dl> | |
| 20 | <dt>size</dt> | |
| 21 | <dd> | |
| 22 | The size of the <i>tuple</i> from which the parentheses are to be removed. | |
| 23 | Valid <i>tuple</i> sizes range from <i>1</i> to <b>BOOST_PP_LIMIT_TUPLE</b>. | |
| 24 | </dd> | |
| 25 | <dt>tuple</dt> | |
| 26 | <dd> | |
| 27 | The <i>tuple</i> from which the parenthesis are removed. | |
| 28 | </dd> | |
| 29 | </dl> | |
| 30 | <h4>Remarks</h4> | |
| 31 | <div> | |
| 32 | The <i>size</i> argument must be the actual size of <i>tuple</i>.<br> | |
| 33 | <br> | |
| 34 | You can | |
| 35 | invoke the variadic version <a href="../topics/variadic_macros.html#VNotation" target="_self"><sup>(v)</sup></a> as BOOST_PP_TUPLE_REM_CTOR(<i>tuple</i>) or | |
| 36 | BOOST_PP_TUPLE_REM_CTOR(<i>size</i>,<i>tuple</i>).<br> | |
