| 8 | The <b>BOOST_PP_ARRAY_REPLACE</b> macro replaces an element in an <i>array</i>. |
| 9 | </div> |
| 10 | <h4>Usage</h4> |
| 11 | <div class="code"> |
| 12 | <b>BOOST_PP_ARRAY_REPLACE</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 | An <i>array</i> to replace an element in. |
| 19 | </dd> |
| 20 | <dt>i</dt> |
| 21 | <dd> |
| 22 | The zero-based position in <i>array</i> of the element to be replaced. |
| 23 | Valid values range from <i>0</i> to <b>BOOST_PP_ARRAY_SIZE</b>(<i>array</i>) - <i>1</i>. |
| 24 | </dd> |
| 25 | <dt>elem</dt> |
| 26 | <dd> |
| 27 | The replacement element. |
| 28 | </dd> |
| 29 | </dl> |
| 30 | <h4>Remarks</h4> |
| 31 | <div> |
| 32 | This macro uses <b>BOOST_PP_WHILE</b> interally. |
| 33 | Therefore, to use the <i>d</i> parameter passed from other macros that use <b>BOOST_PP_WHILE</b>, |
| 34 | see <b>BOOST_PP_ARRAY_REPLACE_D</b>. |
