I was asked to interprete the following C statement:
#define XY(s,m) (&((s*)0)->m)

Out of curiousity was my explanation correct:

Assumption 1: s is a structure
Assumption 2: m is a member of s

s* typecasts the "pointer to a structure s" to a "pointer to s".

The remaining "stuff" would be interpreted as:
the address of member "m" at location "s + 0 "
