The <b>BOOST_PP_LIST_ENUM</b> macro converts a <i>list</i> to a comma-separated list.
|
|
</div>
|
|
<h4>Usage</h4>
|
|
<div class="code">
|
|
<b>BOOST_PP_LIST_ENUM</b>(<i>list</i>)
|
|
</div>
|
|
<h4>Arguments</h4>
|
|
<dl>
|
|
<dt>list</dt>
|
|
<dd>
|
|
The <i>list</i> to be converted.
|
|
</dd>
|
|
</dl>
|
|
<h4>Remarks</h4>
|
|
<div>
|
|
If <i>list</i> is, for example, (<i>a</i>, (<i>b</i>, (<i>c</i>, <b>BOOST_PP_NIL</b>))),
|
|
this macro will produce:
|
|
<div>
|
|
<i>a</i>, <i>b</i>, <i>c</i>
|
|
</div>
|
|
</div>
|
|
<div>
|
|
Previously, this macro could not be used inside <b>BOOST_PP_FOR</b>.
|
|
There is no longer any such restriction.
|
|
It is more efficient, however, to use <b>BOOST_PP_LIST_ENUM_R</b> in such a situation.
