<div style="margin-left: 0px;"> The <b>BOOST_PP_TUPLE_POP_FRONT</b> macro
|
|
pops an element from the beginning of a <i>tuple</i>.</div>
|
|
<h4>Usage</h4>
|
|
<div class="code"> <b>BOOST_PP_TUPLE_POP_FRONT</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> This macro returns <i>tuple</i> after removing the first
|
|
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_FRONT_Z</b> </div>
