| The <b>BOOST_PP_LIST_APPEND</b> macro appends two <i>lists</i>. |
| </div> |
| <h4>Usage</h4> |
| <div class="code"> |
| <b>BOOST_PP_LIST_APPEND</b>(<i>a</i>, <i>b</i>) |
| </div> |
| <h4>Arguments</h4> |
| <dl> |
| <dt>a</dt> |
| <dd> |
| The first <i>list</i>. |
| </dd> |
| <dt>b</dt> |
| <dd> |
| The second <i>list</i>. |
| </dd> |
| </dl> |
| <h4>Remarks</h4> |
| <div> |
| This macro appends two lists. |
| For example, if <i>a</i> is (<i>1</i>, (<i>2</i>, (<i>3</i>, <b>BOOST_PP_NIL</b>))) and <i>b</i> is (<i>4</i>, (<i>5</i>, <b>BOOST_PP_NIL</b>)), |
| this macro will expand to: |
| <div> |
| (<i>1</i>, (<i>2</i>, (<i>3</i>, (<i>4</i>, (<i>5</i>, <b>BOOST_PP_NIL</b>))))) |
| </div> |
| </div> |
| <div> |
| Previously, this macro could not be used inside <b>BOOST_PP_WHILE</b>. |
| There is no longer any such restriction. |
| It is more efficient, however, to use <b>BOOST_PP_LIST_APPEND_D</b> in such a situation. |
