The BOOST_PP_VARIADICS macro specifies whether variadic macro support exists.

Usage

BOOST_PP_VARIADICS
Remarks
The macro is an object-like macro. It is used in internal code to check for the presence of variadic macro support. It can be used by the end-user for the same purpose. The macro equals 1 if variadic macros are supported and 0 if they are not.
