<div style="margin-left: 0px;">
The <b>BOOST_PP_ENUM_PARAMS</b> macro generates a comma-separated list of parameters.
</div>
<h4>Usage</h4>
<div class="code">
<b>BOOST_PP_ENUM_PARAMS</b>(<i>count</i>, <i>param</i>)
</div>
<h4>Arguments</h4>
<dl>
<dt>count</dt>
<dd>
The number of parameters to generate.&nbsp;
Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_REPEAT</b>.
</dd>
<dt>param</dt>
<dd>
The text of the parameter.&nbsp;
<b>BOOST_PP_ENUM_PARAMS</b> concatenates numbers ranging from <i>0</i> to <i>count</i> - <i>1</i>
to generate parameters.
</dd>
</dl>
<h4>Remarks</h4>
<div>
This macro expands to the comma-separated sequence:
<div>
<i>param</i> ## <i>0</i>, <i>param</i> ## <i>1</i>, ... <i>param</i> ## <i>count</i> - <i>1</i>
</div>
</div>
<div>
To use the <i>z</i> parameter passed from other macros that use <b>BOOST_PP_REPEAT</b>, see <b>BOOST_PP_ENUM_PARAMS_Z</b>.
</div>
<div>
Previously, this macro could not be used recursively inside <b>BOOST_PP_REPEAT</b>.&nbsp;
This limitation no longer exists, as the library can automatically detect the next available repetition depth.
