8 The <b>BOOST_PP_ARRAY_INSERT</b> macro inserts an element into an <i>array</i>.
9 </div>
10 <h4>Usage</h4>
11 <div class="code">
12 <b>BOOST_PP_ARRAY_INSERT</b>(<i>array</i>, <i>i</i>, <i>elem</i>)
13 </div>
14 <h4>Arguments</h4>
15 <dl>
16 <dt>array</dt>
17 <dd>
18 The <i>array</i> into which an element is to be inserted.
19 </dd>
20 <dt>i</dt>
21 <dd>
22 The zero-based position in <i>array</i> where an element is to be inserted.&nbsp;
23 Valid values range from <i>0</i> to <b>BOOST_PP_ARRAY_SIZE</b>(<i>array</i>).
24 </dd>
25 <dt>elem</dt>
26 <dd>
27 The element to insert.
28 </dd>
29 </dl>
30 <h4>Remarks</h4>
31 <div>
32 This macro inserts <i>elem</i> before the element at index <i>i</i>.
33 </div>
34 <div>
35 If the operation attempts to create an <i>array</i> that is larger than <b>BOOST_PP_LIMIT_TUPLE</b>,
36 the result is undefined.
37 </div>
38 <div>
39 This macro uses <b>BOOST_PP_WHILE</b> interally.&nbsp;
40 Therefore, to use the <i>d</i> parameter passed from other macros that use <b>BOOST_PP_WHILE</b>,
41 see <b>BOOST_PP_ARRAY_INSERT_D</b>.
