That is not as terrible.
Or maybe a define like:
+ #define SYSCTL_BOUNDED_ARR_READONLY 0,0
int sysctl_bounded_arr(const struct sysctl_bounded_args *, u_int,
int *, u_int, void *, size_t *, void *, size_t);
Which can then be used in-place without confusion.
But whatever we do, it must be documented clearly.
