<h3><a name="BOOST_PP_ENUM_SHIFTED_PARAMS">#define BOOST_PP_ENUM_SHIFTED_PARAMS</a>(COUNT,PARAM)</h3>
<p>Generates a comma separated list of shifted actual parameters.</p>
<p>In other words, expands to the sequence:</p>
<pre>
<a href="cat.htm#BOOST_PP_CAT">BOOST_PP_CAT</a>(PARAM,1), <a href="cat.htm#BOOST_PP_CAT">BOOST_PP_CAT</a>(PARAM,2), ..., <a href="cat.htm#BOOST_PP_CAT">BOOST_PP_CAT</a>(PARAM,<a href="dec.htm#BOOST_PP_DEC">BOOST_PP_DEC</a>(COUNT))
</pre>
<p>For example,</p>
<pre>
<a href="enum_shifted_params.htm#BOOST_PP_ENUM_SHIFTED_PARAMS">BOOST_PP_ENUM_SHIFTED_PARAMS</a>(3,x)
</pre>
<p>expands to:</p>
<pre>
x1, x2
</pre>
<h3>Uses</h3>
<ul>
<li><a href="repeat.htm#BOOST_PP_REPEAT">BOOST_PP_REPEAT</a>()</li>
</ul>
<h3>Rationale</h3>
<ul>
<li>This macro facilitates a typical usage of the library. Shifted parameter
lists are common in template metaprograms.</li>
</ul>
<h3>Test</h3>
