The <b>BOOST_PP_ARRAY_POP_BACK</b> macro pops an element from the end of an <i>array</i>.
|
||
|
</div>
|
||
|
<h4>Usage</h4>
|
||
|
<div class="code">
|
||
|
<b>BOOST_PP_ARRAY_POP_BACK</b>(<i>array</i>)
|
||
|
</div>
|
||
|
<h4>Arguments</h4>
|
||
|
<dl>
|
||
|
<dt>array</dt>
|
||
|
<dd>
|
||
|
The <i>array</i> to pop an element from.
|
||
|
</dd>
|
||
|
</dl>
|
||
|
<h4>Remarks</h4>
|
||
|
<div>
|
||
|
This macro returns <i>array</i> after removing the last element.
|
||
|
If <i>array</i> has no elements, the result of applying this macro is undefined.
|
||
|
</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_ARRAY_POP_BACK_Z</b>
|
||
|
</div>
