Getting the implementation object from a reference

[Steve Brenneis]

I would suggest using _narrow and then test the result using =
CORBA::is_nil.  If it is not nil then a static or C-style cast would be =
safe.

As a side note, it will be nice when all compilers support RTTI and =
dynamic casting.  It should simplify the implementation of _narrow =
significantly.

Greetings,

Having a reference to a CORBA object, I would like to get the associated
implementation object. I am aware that I can use dynamic casting:

   Interface_i *p =3D dynamic_cast<Interface_i*>(i_ptr);
   if(p)
     // ok to use p...

- but what do I do with compilers that do not support run-time type
information??


Regards,

	Ole.
