You would need casts to integer types here:

int lnOffsetX = ((uintptr_t) &foo.x - (uintptr_t) &foo);

Of course, that requires the existence of an object "foo" of the struct
type - while offsetoff works /without/ having any known object of that type.


Usually if there is no compiler-specific intrinsic or built-in,
offsetoff is implemented as something like this:

#define offsetof(TYPE, ELEMENT) ((size_t)&(((TYPE *)0)->ELEMENT))

(This is actually much the same as your pointer maths, with the missing
cast - it's just that we pretend that we have a object of type TYPE at
address 0.)

Technically, this is undefined behaviour (though it will work with most
compilers) - therefore compiles have to provide a method that they know
works for their compiler.


Anyway, the point how you would wrap this all up in a convenient
offsetof "thingy" if you didn't want to make offsetof as a macro.  The
answer, of course, is that you cannot do so with C - you cannot even do
it with C++.
