Question

I want to do for example:

#define macro(a) foo( _blah_, *(dword*)(&a) );
#define macro(a,b) foo( _blah_, *(dword*)(&a) , *(dword*)(&b) );
#define macro(a,b,c) foo( _blah_, *(dword*)(&a) , *(dword*)(&b) , *(dword*)(&c) );

But of course with variable no. of arguments. I essentially want to wrap each argument indiviudally, not pass all the arguments as one __VA_ARGS__ block.

Answer 1

As any other sane person, I advise you to drop the macros, especially with C++11’s variadic templates:

template<class T>
dword& make_dword(T& v){
  return *reinterpret_cast<dword*>(&v);
}

template<class... Args>
void bar(Args&... args){
  foo(_blah_, make_dword(args)...);
}

This should do the trick.

I need to mention that those reinterpret_casts look pretty dubious, though…
