I am confused.
The type of object_decoration.decorattion is a (void*). Why isn't it
sufficient to do it in a naïve and straightforward way?
mark = (uint32_t)(deco->decoration);
add_decoration(&idnums, object, (void*) mark);
Is this twisted pointer arithmetic done in order to avoid cast
between int
and pointer of different size in the code?
I'm not sure why this is done; I simply copied what the existing code
already
did.
Even if that is the case,
doesn't "(uint32_t *)deco->decoration - (uint32_t *)NULL" mean the
value
range for deco->decoration is one-fourth of U32?
I'd imagine so, yes
