| 8 | The <b>BOOST_PP_COMPL</b> macro performs a bitwise inversion (bitwise <i>NOT</i> or one's complement) on its operand. |
|---|
| 9 | </div> |
|---|
| 10 | <h4>Usage</h4> |
|---|
| 11 | <div class="code"> |
|---|
| 12 | <b>BOOST_PP_COMPL</b>(<i>x</i>) |
|---|
| 13 | </div> |
|---|
| 14 | <h4>Arguments</h4> |
|---|
| 15 | <dl> |
|---|
| 16 | <dt>x</dt> |
|---|
| 17 | <dd> |
|---|
| 18 | The value to be converted. |
|---|
| 19 | This value must expand to <i>0</i> or <i>1</i>. |
|---|
| 20 | </dd> |
|---|
| 21 | </dl> |
|---|
| 22 | <h4>Remarks</h4> |
|---|
| 23 | <div> |
|---|
| 24 | If <i>x</i> is <i>0</i>, this macro expands to <i>1</i>. |
|---|
| 25 | If <i>x</i> is <i>1</i>, this it expands to <i>0</i>. |
|---|
| 26 | </div> |
|---|
| 27 | <div> |
|---|
| 28 | This macro <i>does not</i> perform a boolean conversion on its operand before performing the inversion <i>OR</i> operation. |
|---|
| 29 | If that conversion is necessary, use <b>BOOST_PP_NOT</b> instead. |
