8 | <div style="margin-left: 0px;"> The <b>BOOST_PP_SEQ_REST_N</b> macro | |
9 | expands to a <i>seq</i> of all but the first <i>n</i> elements of a <i>seq</i>. | |
10 | </div> | |
11 | <h4> Usage </h4> | |
12 | <div class="code"> <b>BOOST_PP_SEQ_REST_N</b>(<i>n</i>, <i>seq</i>) </div> | |
13 | <h4> Arguments </h4> | |
14 | <dl> | |
15 | <dt>n</dt> | |
16 | <dd> The number of elements to remove. </dd> | |
17 | <dt>seq</dt> | |
18 | <dd> The <i>seq</i> from which the elements are to be removed. </dd> | |
19 | </dl> | |
20 | <h4> Remarks </h4> | |
21 | <div> This macro extracts <i>n</i> elements from the beginning of <i>seq</i> | |
22 | and returns the remainder of <i>seq</i> as a new <i>seq.<br> | |
23 | <br> | |
24 | </i>It is undefined behavior if <i>n </i>is greater or equal to the size | |
25 | of the <i>seq</i>. </div> | |
