I don't think so.
The only type I know that is guaranteed to be capable of storing the whole
pointer is a void*. But void* is menat to be not that pure address number in
the properties, it is meant to store some arbitrary property, which is ok so
far.
But I believe that for our problem, it would be sufficient if we just convert
that address to a string and take this string as an id.
That saied how about something like
stringstream s;
s << this;
and then take
s.str()
as that id?
