What is the difference between Boost smart pointers and std smart pointers?

Question

So, I\'d like to use smart pointers instead of raw and almost every topic on SO says about Boost library. But std has such things as std::auto_ptr and std::sh

Answer 1

Basically Boost did shared_ptr first. You may note that many of the new container classes in C++11 were in Boost long ago. I would expect this pattern to continue with the next revisions of the C++ standard, too. Boost supports older C++ compilers that don't talk C++11, which is a big benefit.

Incidentally, std::auto_ptr is deprecated in C++11, which brings in std::shared_ptr and std::unique_ptr instead, which are both significantly more useful.
