| The <b>BOOST_PP_OR</b> macro expands to the logical <i>OR</i> of its operands. |
| </div> |
| <h4>Usage</h4> |
| <div class="code"> |
| <b>BOOST_PP_OR</b>(<i>p</i>, <i>q</i>) |
| </div> |
| <h4>Arguments</h4> |
| <dl> |
| <dt>p</dt> |
| <dd> |
| The left operand of the operation. |
| Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>. |
| </dd> |
| <dt>q</dt> |
| <dd> |
| The right operand of the operation. |
| Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>. |
| </dd> |
| </dl> |
| <h4>Remarks</h4> |
| <div> |
| If either <i>p</i> or <i>q</i> is non-zero, this macro expands to <i>1</i>. |
| Otherwise, it expands to <i>0</i>. |
| </div> |
| <div> |
| This macro performs a boolean conversion on each operand before performing the logical <i>OR</i> operation. |
| If that conversion is not necessary, use <b>BOOST_PP_BITOR</b> instead. |
| </div> |
