<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>)</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.&nbsp;
If <i>tuple</i> has only a single element, it remains unchanged since
a&nbsp;<i>tuple </i>must have at least one element.</div>
<div> This macro uses <b>BOOST_PP_REPEAT</b> internally.&nbsp; 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>
