| 7 | <div style="margin-left: 0px;"> The <b>BOOST_PP_VARIADICS </b>macro specifies whether variadic macro support exists.<br> | |

| 10 | <div class="code"><b>BOOST_PP_VARIADICS</b><br> | |
| 11 | </div><b>Remarks</b> | |
| 12 | <div> The macro is an <i>object-like</i> macro. It is used in internal | |
| 13 | code to check for the presence of variadic macro support. It can be | |
| 14 | used by the end-user for the same purpose. The macro equals 1 if | |
| 15 | variadic macros are supported and 0 if they are not. </div><b>Requirements</b> | |
