| <div style="margin-left: 0px;"> |
| The <b>BOOST_PP_ENUM_PARAMS_WITH_DEFAULTS</b> macro generates a comma-separated list of parameters with default arguments. |
| </div> |
| <h4>Usage</h4> |
| <div class="code"> |
| <b>BOOST_PP_ENUM_PARAMS_WITH_DEFAULTS</b>(<i>count</i>, <i>param</i>, <i>def</i>) |
| </div> |
| <h4>Arguments</h4> |
| <dl> |
| <dt>count</dt> |
| <dd> |
| The number of parameters to generate. |
| Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_REPEAT</b>. |
| </dd> |
| <dt>param</dt> |
| <dd> |
| The text of the parameter. |
| <b>BOOST_PP_ENUM_PARAMS_WITH_DEFAULTS</b> concatenates numbers ranging from <i>0</i> to <i>count</i> - <i>1</i> |
| to generate parameters. |
| </dd> |
| <dt>def</dt> |
| <dd> |
| The default value that trails each parameter. |
| <b>BOOST_PP_ENUM_PARAMS_WITH_DEFAULTS</b> concatenates numbers ranging from <i>0</i> to <i>count</i> - <i>1</i> |
| to generate default arguments. |
| </dd> |
| </dl> |
| <h4>Remarks</h4> |
| <div> |
| This macro expands to the comma-separated sequence: |
| <div> |
| <i>param</i> ## <i>0</i> = <i>def</i> ## <i>0</i>, <i>param</i> ## <i>1</i> = <i>def</i> ## <i>1</i>, ... <i>param</i> ## <i>count</i> - <i>1</i> = <i>def</i> ## <i>count</i> - <i>1</i> |
| </div> |
| </div> |
| <div> |
| Previously, this macro could not be used recursively inside <b>BOOST_PP_REPEAT</b>. |
| This limitation no longer exists, as the library can automatically detect the next available repetition depth. |
| </div> |
| <div> |
| This macro is deprecated. |
| It only exists for backward compatibility. |
| Use <b>BOOST_PP_ENUM_BINARY_PARAMS</b> instead: |
| <div> |
| <b>BOOST_PP_ENUM_BINARY_PARAMS</b>(<i>count</i>, <i>param</i>, = <i>def</i>) |
| </div> |
| </div> |
