No, va_arg is a function. > Why is this extra step necessary and why won't simple casting not work? You should never directly work with _argptr. It's not guaranteed to be a simple pointer. For example, I believe that GCC will sometimes use registers (God only knows WHY). var_arg!(T) will convert _argptr into the type you specify and it will also advance _argptr to the next argument. -- Daniel
