| 8 | The <b>BOOST_PP_ENUM_TRAILING_PARAMS</b> macro generates a comma-separated list of parameters with a leading comma. | |
| 9 | </div> | |
| 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. | |
| 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. | |
| 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> | |
| 29 | <div> | |
| 30 | This macro expands to the comma-separated sequence: | |
| 31 | <div> | |
| 32 | , <i>param</i> ## <i>0</i>, <i>param</i> ## <i>1</i>, ... <i>param</i> ## <i>count</i> - <i>1</i> | |
| 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>. | |
