8 | The <b>BOOST_PP_LIST_REST_N_D</b> macro expands to a <i>list</i> of all but the first <i>count</i> elements of a <i>list</i>. | |
9 | It reenters <b>BOOST_PP_WHILE</b> with maximum efficiency. | |
10 | </div> | |
11 | <h4>Usage</h4> | |
12 | <div class="code"> | |
13 | <b>BOOST_PP_LIST_REST_N_D</b>(<i>d</i>, <i>count</i>, <i>list</i>) | |
14 | </div> | |
15 | <h4>Arguments</h4> | |
16 | <dl> | |
17 | <dt>d</dt> | |
18 | <dd> | |
19 | The next available <b>BOOST_PP_WHILE</b> iteration. | |
20 | </dd> | |
21 | <dt>count</dt> | |
22 | <dd> | |
23 | The number of elements to remove from the beginning of <i>list</i>. | |
24 | </dd> | |
25 | <dt>list</dt> | |
26 | <dd> | |
27 | The <i>list</i> from which the elements are extracted. | |
28 | </dd> | |
29 | </dl> | |
30 | <h4>Remarks</h4> | |
31 | <div> | |
32 | This macro removes <i>count</i> elements from the beginning of <i>list</i> and returns the remainder as a <i>list</i> | |
