- <div style="margin-left: 0px;"> The <b>BOOST_PP_TUPLE_POP_BACK</b> macro
- pops an element from the end of an <i>tuple</i>.</div>
- <h4>Usage</h4>
- <div class="code"> <b>BOOST_PP_TUPLE_POP_BACK</b>(<i>tuple</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> to pop an element from.</dd>
- </dl>
- <h4>Remarks</h4>
- <div style="background-color: white;"> This macro returns <i>tuple</i>
- after removing the last element. If <i>tuple</i> has only a single
- element, it remains unchanged since a <i>tuple </i>must have at
- least one element.</div>
- <div> This macro uses <b>BOOST_PP_REPEAT</b> internally. Therefore,
- to use the <i>z</i> parameter passed from other macros that use <b>BOOST_PP_REPEAT</b>,
- see <b>BOOST_PP_TUPLE_POP_BACK_Z</b> </div>
