The <b>BOOST_PP_CAT</b> macro concatenates its arguments after they have been expanded.
</div>
<h4>Usage</h4>
<div class="code">
<b>BOOST_PP_CAT</b>(<i>a</i>, <i>b</i>)
</div>
<h4>Arguments</h4>
<dl>
<dt>a</dt>
<dd>
The left operand of the concatenation.
</dd>
<dt>b</dt>
<dd>
The right operand of the concatenation.
</dd>
</dl>
<h4>Remarks</h4>
<div>
The preprocessor token-pasting operator (<b>##</b>) prevents arguments from expanding.
This macro allows its arguments to expand before concatenation.
</div>
<div>
Concatenation must not result in an invocation of a macro that uses <b>BOOST_PP_CAT</b>.
If that happens, <b>BOOST_PP_CAT</b> will not expand the second time.
