Probably this should either return a bool indicating success/failure, or at
least set set |*addr_out| to something predictable (and invalid), in the case
that 1.1 isn't available.

(I guess the same could be said for |GetAnyAddress()|. Oops.)

[Sergey Ulanov, 2012/03/21 18:14:51]

Yes, agree. Done. 
Right, that's why didn't make it return bool in the first place. Is it too late
to fix GetAnyAddress()?

[viettrungluu, 2012/03/22 04:54:34]

Fixing GetAnyAddress() should be fine.

In general, changes to the C++ wrappers of the following form should be fine
(esp. for Dev interfaces):
- Changes that don't break users of the wrappers (adding a bool return should
fall into this category).
- Changes that break users in an obvious way (e.g., during compile!) and for
which the changes to the code using the wrappers aren't too onerous.

Done.
