8 | The <b>BOOST_PP_BITOR</b> macro expands to the bitwise <i>OR</i> of its operands. | |
9 | </div> | |
10 | <h4>Usage</h4> | |
11 | <div class="code"> | |
12 | <b>BOOST_PP_BITOR</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. | |
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. | |
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>, this macro expands to <i>1</i>. | |
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. | |
34 | If that conversion is necessary, use <b>BOOST_PP_OR</b> instead. | |
