<div style="margin-left: 0px;"> The <b>BOOST_PP_ARRAY_ENUM</b>
|
|
macro converts an <i>array</i> to its comma-separated elements.
|
|
The comma-separated elements are in the form of <i>variadic data</i>.<br>
|
|
</div>
|
|
<h4> Usage </h4>
|
|
<div class="code"> <b>BOOST_PP_ARRAY_ENUM</b>(<i>array</i>) </div>
|

<h4> Arguments </h4>
|
|
<dl>
|
|
<dt>array</dt>
|
|
<dd> The <i>array</i> whose elements are to be converted. </dd>
|
|
</dl>
|
|
<h4> Remarks </h4>
|
|
<div> This macro expands to a comma-separated list of the elements
|
|
in <i>array</i>.
|
|
For example, <b>BOOST_PP_ARRAY_ENUM</b>((3,(<i>x,</i><i>y,</i><i>z</i>)))
|
|
expands
|
|
to...
|
|
<div> <i>x</i>, <i>y</i>, <i>z<br>

|
</i> </div>

|
|
<i>data</i> will be empty.</p>
