| The <b>BOOST_PP_LIST_CAT_D</b> macro concatenates all elements in a <i>list</i>. |
| It reenters <b>BOOST_PP_WHILE</b> with maximum efficiency. |
| </div> |
| <h4>Usage</h4> |
| <div class="code"> |
| <b>BOOST_PP_LIST_CAT_D</b>(<i>d</i>, <i>list</i>) |
| </div> |
| <h4>Arguments</h4> |
| <dl> |
| <dt>d</dt> |
| <dd> |
| The next available <b>BOOST_PP_WHILE</b> iteration. |
| </dd> |
| <dt>list</dt> |
| <dd> |
| The <i>list</i> whose elements are to be concatenated. |
| </dd> |
| </dl> |
| <h4>Remarks</h4> |
| <div> |
| Elements are concatenated left-to-right starting with index <i>0</i>. |
