- <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>
