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