I assume you used a union in struct xucred because a pointer has a different size on different architectures? You could use something like this:
pid_t cr_pid;
u_char _cr_unused1[sizeof(void *)-sizeof(pid_t)];
But perhaps that's not really an improvement.

sure
pid_t cr_pid;
u_char _cr_unused1[sizeof(void *)-sizeof(pid_t)];But perhaps that's not really an improvement.
my variant is better for static struct xucred initialization
thanks
