<h2><a name="BOOST_PP_COMMA">#define BOOST_PP_COMMA</a>()</h2>
<p>Expands to a comma. Can be used with <a href="if.htm#BOOST_PP_IF">BOOST_PP_IF</a>().</p>
<p>Expands to a comma.</p>
<p>Commas need special handling in preprocessor code, because commas are used
for separating macro parameters.</p>
<p>For example,</p>
<pre>
<a href="if.htm#BOOST_PP_IF">BOOST_PP_IF</a>(1,<a href="comma.htm#BOOST_PP_COMMA">BOOST_PP_COMMA</a>,<a href="empty.htm#BOOST_PP_EMPTY">BOOST_PP_EMPTY</a>)()
</pre>
<p>expands to a comma.</p>
