| <div style="margin-left: 0px;"> The <b>BOOST_PP_TUPLE_INSERT</b> macro |
| inserts an element into an <i>tuple</i>.</div> |
| <h4>Usage</h4> |
| <div class="code"> <b>BOOST_PP_TUPLE_INSERT</b>(<i>tuple</i>, <i>i</i>, <i>elem</i>) |
| <a href="../topics/variadic_macros.html#VNotation"><sup>(v)</sup></a></div> |
| <h4>Arguments</h4> |
| <dl> |
| <dt>tuple</dt> |
| <dd> The <i>tuple</i> into which an element is to be inserted. </dd> |
| <dt>i</dt> |
| <dd> The zero-based position in <i>tuple</i> where an element is to be |
| inserted. Valid values range from <i>0</i> to <b>BOOST_PP_TUPLE_SIZE</b>(<i>tuple</i>).</dd> |
| <dt>elem</dt> |
| <dd> The element to insert. </dd> |
| </dl> |
| <h4>Remarks</h4> |
| <div> This macro inserts <i>elem</i> before the element at index <i>i</i>. |
| </div> |
| <div> If the operation attempts to create an <i>tuple</i> that is larger |
| than <b>BOOST_PP_LIMIT_TUPLE</b>, the result is undefined.</div> |
| <div> This macro uses <b>BOOST_PP_WHILE</b> interally. Therefore, to |
| use the <i>d</i> parameter passed from other macros that use <b>BOOST_PP_WHILE</b>, |
| see <b>BOOST_PP_TUPLE_INSERT_D</b>.</div> |
