什么是加速智能指针和std智能指针之间的区别？ [英] What is the difference between Boost smart pointers and std smart pointers?

问题描述

所以，我想使用智能指针，而不是原始的，几乎每一个主题的SO说，大约Boost库。但性病有这样的事情的std :: auto_ptr的和的std :: shared_ptr的。
为什么提升？有什么区别？

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::shared_ptr. Why Boost? What is the difference?

推荐答案

基本上升压做的shared_ptr 第一。你可能注意到，许多新的容器类在C ++ 11人升压很久以前。我希望这种模式继续与C ++标准的下一个版本了。升压支持旧的C ++编译器不谈论C ++ 11，这是一个很大的好处。

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.

顺便说一句，的std :: auto_ptr的是德precated在C ++ 11，这带来了的std :: shared_ptr的和的std ::的unique_ptr 来代替，这两者都是显著更加有用。

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.
