I believe you could add a code_helper constructor for another type, maybe e=
ven
"int"?  Then the "default" value for the code_helper argument for the
legitimate address hook function would just look like "code_helper =3D 0".

Maybe that's too error-prone and a pointer-type or some entirely different =
type
would be better. I might have misunderstood things of course, but that's wh=
at I
mean by "or something".=
