   8                 The <b>BOOST_PP_ENUM_TRAILING_PARAMS_Z</b> macro generates a comma-separated list of parameters with a leading comma.&nbsp;
   9                 It reenters <b>BOOST_PP_REPEAT</b> with maximum efficiency.
  10         </div>
  11         <h4>Usage</h4>
  12                 <div class="code">
  13                         <b>BOOST_PP_ENUM_TRAILING_PARAMS_Z</b>(<i>z</i>, <i>count</i>, <i>param</i>)
  14                 </div>
  15         <h4>Arguments</h4>
  16                 <dl>
  17                         <dt>z</dt>
  18                         <dd>
  19                                 The next available <b>BOOST_PP_REPEAT</b> dimension.
  20                         </dd>
  21                         <dt>count</dt>
  22                         <dd>
  23                                 The number of parameters to generate.&nbsp;
  24                                 Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_REPEAT</b>.
  25                         </dd>
  26                         <dt>param</dt>
  27                         <dd>
  28                                 The text of the parameter.&nbsp;
  29                                 <b>BOOST_PP_ENUM_TRAILING_PARAMS_Z</b> concatenates numbers ranging from <i>0</i> to <i>count</i> - <i>1</i>
  30                                 to generate parameters.
  31                         </dd>
  32                 </dl>

  35                         This macro expands to the comma-separated sequence:

  37                                 , <i>param</i> ## <i>0</i>, <i>param</i> ## <i>1</i>, ... <i>param</i> ## <i>count</i> - <i>1</i>
  38                         </div>
