| The <b>BOOST_PP_SEQ_FOR_EACH_R</b> macro repeats a macro for each element in a <i>seq</i>. |
| It reenters <b>BOOST_PP_FOR</b> with maximum efficiency. |
| </div> |
| <h4> |
| Usage |
| </h4> |
| <div class="code"> |
| <b>BOOST_PP_SEQ_FOR_EACH_R</b>(<i>r</i>, <i>macro</i>, <i>data</i>, <i>seq</i>) |
| </div> |
| <h4> |
| Arguments |
| </h4> |
| <dl> |
| <dt>r</dt> |
| <dd> |
| The next available <b>BOOST_PP_FOR</b> repetition. |
| </dd> |
| <dt>macro</dt> |
| <dd> |
| A ternary macro of the form <i>macro</i>(<i>r</i>, <i>data</i>, <i>elem</i>). |
| This macro is expanded by <b>BOOST_PP_SEQ_FOR_EACH</b> with each element in <i>seq</i>. |
| It is expanded with the next available <b>BOOST_PP_FOR</b> repetition, the |
| auxiliary <i>data</i>, and the current element. |
| </dd> |
| <dt>data</dt> |
| <dd> |
| Auxiliary data passed to <i>macro</i>. |
| </dd> |
| <dt>seq</dt> |
| <dd> |
| The <i>seq</i> for which <i>macro</i> will be invoked on each element. |
| </dd> |
| </dl> |
| <h4> |
| Remarks |
| </h4> |
| <div> |
| This macro is a repetition construct. If <i>seq</i> is (<i>a</i>)(<i>b</i>)(<i>c</i>), |
| it expands to the sequence: |
| <div> |
| <i>macro</i>(<i>r</i>, <i>data</i>, <i>a</i>) <i>macro</i>(<i>r</i>, <i>data</i>, |
| <i>b</i>) <i>macro</i>(<i>r</i>, <i>data</i>, <i>c</i>) |
