Thanks for the link, but that doesn't explain the usage.
As I read it, the FindTable declaration means that the data-structure
pointed to is read-only, and that the pointer value itself is also
But making a pointer value read-only is something only useful to the
internals of a method, and should make no difference to the API signature.
