The <b>BOOST_PP_XOR</b> macro expands to the logical <i>XOR</i> of its operands.
|
|
</div>
|
|
<h4>Usage</h4>
|
|
<div class="code">
|
|
<b>BOOST_PP_XOR</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 exclusively, 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>XOR</i> operation.
|
|
If that conversion is not necessary, use <b>BOOST_PP_BITXOR</b> instead.
|
|
</div>
