| 8 | The <b>BOOST_PP_ENUM_SHIFTED_PARAMS_Z</b> macro generates a comma-separated, shifted list of parameters. |
| 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_SHIFTED_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. |
| 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. |
| 29 | <b>BOOST_PP_ENUM_SHIFTED_PARAMS_Z</b> concatenates numbers ranging from <i>1</i> to <i>count</i> - <i>1</i> |
| 30 | to generate parameters. |
| 31 | </dd> |
| 32 | </dl> |
| 33 | <h4>Remarks</h4> |
| 34 | <div> |
| 35 | This macro expands to the comma-separated sequence: |
| 36 | <div> |
| 37 | <i>param</i> ## <i>1</i>, ... <i>param</i> ## <i>count</i> - <i>1</i> |
| 38 | </div> |
| 39 | </div> |
