I know this is an old topic, but how would you do this when some of the
union arguments are arrays, like, for example, the in6_addr structure:

struct in6_addr
  {
    union
      {
    uint8_t u6_addr8[16];
    uint16_t u6_addr16[8];
    uint32_t u6_addr32[4];
      } in6_u;
#define s6_addr         in6_u.u6_addr8
#define s6_addr16       in6_u.u6_addr16
#define s6_addr32       in6_u.u6_addr32
  };
