| 8 | The <b>BOOST_PP_RPAREN</b> macro expands to a right parenthesis. |

| 10 | <h4>Usage</h4> |
| 11 | <div class="code"> |
| 12 | <b>BOOST_PP_RPAREN</b>() |
| 13 | </div> |
| 14 | <h4>Remarks</h4> |
| 15 | <div> |
| 16 | The preprocessor interprets parentheses as delimiters in macro invocations. |
| 17 | Because of this, parentheses require special handling. |
