  10. <h4>Usage</h4>
  11. <div class="code">
  12. <b>BOOST_PP_ENUM_TRAILING_PARAMS</b>(<i>count</i>, <i>param</i>)
  13. </div>
  14. <h4>Arguments</h4>
  15. <dl>
  16. <dt>count</dt>
  17. <dd>
  18. The number of parameters to generate.&nbsp;
  19. Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_REPEAT</b>.
  20. </dd>
  21. <dt>param</dt>
  22. <dd>
  23. The text of the parameter.&nbsp;
  24. <b>BOOST_PP_ENUM_TRAILING_PARAMS</b> concatenates numbers ranging from <i>0</i> to <i>count</i> - <i>1</i>
  25. to generate parameters.
  26. </dd>
  27. </dl>
  28. <h4>Remarks</h4>

  30. This macro expands to the comma-separated sequence:

  33. </div>
  34. </div>
  35. <div>
  36. To use the <i>z</i> parameter passed from other macros that use <b>BOOST_PP_REPEAT</b>, see <b>BOOST_PP_ENUM_TRAILING_PARAMS_Z</b>.
