Is there any way to use varargs with boost::format?

Question

I'm kinda loathe to use a fixed-sized buffer and the vnsprintf usual suspects.

Would something like this work to have boost::format work with a variable argument list?

Sadly, I cannot use anything from C++11.

void formatIt(const char* msg, ...) {
        va_list args;
        va_start(args, msg);
        boost::format f(msg);
        for loop somehow {                  
          f % va_arg(args, const char *);   //does this work?           
        }
        va_end(args);
}

I use this:

inline static std::string FormatStringRecurse(boost::format& message)
{
    return message.str();
}

template <typename TValue, typename... TArgs>
std::string FormatStringRecurse(boost::format& message, TValue&& arg, TArgs&&... args)
{
   message % std::forward<TValue>(arg);
   return FormatStringRecurse(message, std::forward<TArgs>(args)...);
}

template <typename... TArgs>
std::string FormatString(const char* fmt, TArgs&&... args)
{
    using namespace boost::io;
    boost::format message(fmt);
    return FormatStringRecurse(message, std::forward<TArgs>(args)...);
}
