Can I overload throw or return?

It's said I can't throw an ostream object, so maybe I can overload "throw"
for my basic_ostream derived class?

With the exception of a few special cases, you can "throw" any object
that you can "return".

You can't throw ostreams because you can't copy them. The object
you throw must have valid copy semantics.

So I see. But can I overload throw or return? Does C++ support that?

What exactly do you mean by "overload"? Like operator overloading?

No.


Besides, I'm not sure what you think that would accomplish.
What do you want to do?
