Re: [Boost-users] Preprocessor Question

Thanks for the solution,

but it was actually failing in getting number of arguments to the macro.

warning C4003: not enough actual parameters for macro 'PP_ARG_N'

so PP_NARG evaluates to nothing and subsequently everything fails.

Please note that the VC preprocessor does not support variadic macros, which makes the valid implementation of PP_NARG() fail. Regards Hartmut ------------------- Meet me at BoostCon http://boostcon.com
