Is auto_ptr deprecated?

Question

1. Will auto_ptr be deprecated in incoming C++ standard?
2. Should unique_ptr be used for ownership transfer instead of shared_ptr?
3. If unique_ptr is not in

Answer 1

Yes, as of today auto_ptr will be deprecated in C++0x and you should use unique_ptr instead. From the latest draft standard (n3035), section D.9

The class template auto_ptr is deprecated. [ Note: The class template unique_ptr (20.9.10) provides a better solution. —end note ]

Until the standard is ratified, it's always possible that the committee will revise this decision although I feel that is unlikely for this decision.
