P99_FOR in C++11

Question

I am using the P99_FOR macro defined in P99 in my C99 code in order to iterate over VA_ARGS. It works perfectly.

P99_FOR(NAME, N, OP, FUNC,...)

Now I want to migrate to C++11 and I was wondering if there is any macro similar to P99_FOR.

Here is my code in C99:

#ifndef __cplusplus

    #include "p99/p99.h"

    #undef P00_VASSIGN
    #define P00_VASSIGN(NAME, X, I) NAME[I] = X

    #define FOREACH(x, y, z, u, ...) P99_FOR(x, y, z, u, __VA_ARGS__);

#else

    #define FOREACH(x, y, z, u, ...) ???  // C++ equivalent

#endif

#define set_OCTET_STRING(type, numParams, ...) { \
        FOREACH(type, numParams, P00_SEP, P00_VASSIGN, __VA_ARGS__); \
}

For example set_OCTET_STRING(myVar->speed, 3, 34, 10, 11) will expand to:

myVar->speed[0] = 34; myVar->speed[1] = 10; myVar->speed[2] = 11;
