Oops, sorry about that blank message.

If you have a struct

struct {
       int b;
       char c;
} *a;

and you have an expression a->b somewhere in your program,

the compiler generally gets the address of "a" into some register and
adds the offset of "b" within the struct. That gives address of a->b.

mov ebx, a
mov edx, [ebx + 0]; in this case.

or something like that.

But of course, the assembly code may vary between compilers.
