| 8 | The <b>BOOST_PP_ENUM_TRAILING_BINARY_PARAMS</b> macro generates a comma-separated list of binary parameters with a leading comma. |
|---|
| 9 | </div> |
|---|
| 10 | <h4>Usage</h4> |
|---|
| 11 | <div class="code"> |
|---|
| 12 | <b>BOOST_PP_ENUM_TRAILING_BINARY_PARAMS</b>(<i>count</i>, <i>p1</i>, <i>p2</i>) |
|---|
| 13 | </div> |
|---|
| 14 | <h4>Arguments</h4> |
|---|
| 15 | <dl> |
|---|
| 16 | <dt>count</dt> |
|---|
| 17 | <dd> |
|---|
| 18 | The number of parameters to generate. |
|---|
| 19 | Valid values range from <i>0</i> to <b>BOOST_PP_LIMIT_REPEAT</b>. |
|---|
| 20 | </dd> |
|---|
| 21 | <dt>p1</dt> |
|---|
| 22 | <dd> |
|---|
| 23 | The text of the first part of the parameter. |
|---|
| 24 | <b>BOOST_PP_ENUM_TRAILING_BINARY_PARAMS</b> concatenates numbers ranging from <i>0</i> to <i>count</i> - <i>1</i> |
|---|
| 25 | to generate parameters. |
|---|
| 26 | </dd> |
|---|
| 27 | <dt>p2</dt> |
|---|
| 28 | <dd> |
|---|
| 29 | The text of the first part of the parameter. |
|---|
| 30 | <b>BOOST_PP_ENUM_TRAILING_BINARY_PARAMS</b> concatenates numbers ranging from <i>0</i> to <i>count</i> - <i>1</i> |
|---|
| 31 | to generate parameters. |
|---|
| 32 | </dd> |
|---|
| 33 | </dl> |
|---|
| 34 | <h4>Remarks</h4> |
|---|
| 35 | <div> |
|---|
| 36 | This macro expands to the comma-separated sequence: |
|---|
| 37 | <div> |
|---|
| 38 | , <i>p1</i> ## <i>0</i> <i>p2</i> ## <i>0</i>, <i>p1</i> ## <i>1</i> <i>p2</i> ## <i>1</i>, ... <i>p1</i> ## <i>count</i> - <i>1</i> <i>p2</i> ## <i>count</i> - <i>1</i> |
|---|
| 39 | </div> |
|---|
| 40 | </div> |
|---|
| 41 | <div> |
|---|
| 42 | To use the <i>z</i> parameter passed from other macros that use <b>BOOST_PP_REPEAT</b>, see <b>BOOST_PP_ENUM_TRAILING_BINARY_PARAMS_Z</b>. |
