The <b>BOOST_PP_NOT</b> macro performs a logical <i>NOT</i> on its operand.
|
||
|
|
</div>
|
||
|
|
<h4>Usage</h4>
|
||
|
|
<div class="code">
|
||
|
|
<b>BOOST_PP_NOT</b>(<i>x</i>)
|
||
|
|
</div>
|
||
|
|
<h4>Arguments</h4>
|
||
|
|
<dl>
|
||
|
|
<dt>x</dt>
|
||
|
|
<dd>
|
||
|
|
The value to be converted.
|
||
|
|
Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_MAG</b>.
|
||
|
|
</dd>
|
||
|
|
</dl>
|
||
|
|
<h4>Remarks</h4>
|
||
|
|
<div>
|
||
|
|
If <i>x</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 its operand before performing the logical <i>NOT</i> operation.
|
||
|
|
If that conversion is not necessary, use <b>BOOST_PP_COMPL</b> instead.
|
||
|
|
</div>
