How best to do this?
In a word or two, don't. This is basic OOP: all accesses to an object should
be via its (possibly virtual) member functions. There's nothing to stop you
from defining
virtual Dog_t Base_t::as_dog() { return nullptr; }
in the base class, and overriding it as
virtual Dog_t Dog_t::as_dog() { return this; }
in the derived class. If you really need to...
Thx, just tried this out, but it's not of much help as one has to know the
type in advance, ie. at compile time.
Can I remind you that this list is for specific GCC help, not C++ language
issues?
Thanks.
Oh, sorry, I forgot. Can you recommend a mailing list where such issues are
discussed? Thx.
