What are guidelines for using std::unique_ptr?

For sure one should not use it when pointer is shared among other objects, modules. But meybe there are some other guidelines?

hope this question is not a duplicate.

`for member pointer inside class` - ownership determines that - and yes, it is a dupe. – Luchian Grigore Feb 14 '13 at 08:26
I'd say: use it whenever you need an owning pointer but don't need shared ownership. – ereOn Feb 14 '13 at 08:26

There are typical use cases on the reference page for [`unique_ptr`](http://en.cppreference.com/w/cpp/memory/unique_ptr). – hmjd Feb 14 '13 at 08:32

@R.MartinhoFernandes Not sure I agree with Herb here. I don't really see what `unique_ptr` buys you in this case. Either way, you have to define a non-inline destructor. – James Kanze Feb 14 '13 at 08:59
I am going to close this, as being not so constructive... thanks for the comments! – fen Feb 14 '13 at 09:22
