Hello again,
does shared_from_this() also guarantee that it never throws?
No, it can throw bad_weak_ptr.
<http://boost.org/libs/smart_ptr/smart_ptr.htm> states that only std::bad_alloc is thrown - if anything is thrown at all. Am I misreading that?
That's talking about the smart pointer classes. shared_from_this is a method of enable_shared_from_this, which isn't a smart pointer.
And reading the documentation for weak_ptr, it's not clear to me when a bad_weak_ptr exception is thrown at all. All weak_ptr functions are documented to never throw.
It's thrown by the shared_ptr constructor that takes a weak_ptr argument. - -- Frank -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFH6k8R5vihyNWuA4URAsOqAKDA20XnxM+S95VOGXcr7t0JhwDfNwCghUZA 2EODtZcRe3M8JrOXgFNHVkE= =70v9 -----END PGP SIGNATURE-----
