- <div style="margin-left: 0px;"> The <b>BOOST_PP_TUPLE_REMOVE</b> macro
- removes an element from a <i>tuple</i>.</div>
- <h4>Usage</h4>
- <div class="code"> <b>BOOST_PP_TUPLE_REMOVE</b>(<i>tuple</i>, <i>i</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> from which an element is to be removed.</dd>
- <dt>i</dt>
- <dd> The zero-based position in <i>tuple</i> of the element to be
- removed. Valid values range from <i>0</i> to <b>BOOST_PP_TUPLE_SIZE</b>(<i>tuple</i>)
- - <i>1</i>. If <i>tuple</i> has only a single element, it remains
- unchanged since a <i>tuple </i>must have at least one element.</dd>
- </dl>
- <h4>Remarks</h4>
- <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_REMOVE_D</b>.</div>
