   9                 The <b>BOOST_PP_BITXOR</b> macro expands to the bitwise <i>XOR</i> of its operands.
  10         </div>
  11         <h4>Usage</h4>
  12                 <div class="code">
  13                         <b>BOOST_PP_BITXOR</b>(<i>x</i>, <i>y</i>)
  14                 </div>
  15         <h4>Arguments</h4>
  16                 <dl>
  17                         <dt>x</dt>
  18                         <dd>
  19                                 The left operand of the operation.&nbsp;
  20                                 This value must expand to <i>0</i> or <i>1</i>.
  21                         </dd>
  22                         <dt>y</dt>
  23                         <dd>
  24                                 The right operand of the operation.&nbsp;
  25                                 This value must expand to <i>0</i> or <i>1</i>.
  26                         </dd>
  27                 </dl>
  28         <h4>Remarks</h4>
  29                 <div>
  30                         If either <i>x</i> or <i>y</i> is <i>1</i> exclusively, this macro expands to <i>1</i>.&nbsp;
  31                         Otherwise, it expands to <i>0</i>.
  32                 </div>
  33                 <div>
  34                         This macro <i>does not</i> perform a boolean conversion on either operand before performing the bitwise <i>OR</i> operation.&nbsp;
  35                         If that conversion is necessary, use <b>BOOST_PP_XOR</b> instead.
  36                 </div>
