boost :: scoped_ptr的和std ::的unique_ptr的区别

是之间的唯一不同boost::scoped_ptr和std::unique_ptr的事实std::unique_ptr有移动的语义，而boost::scoped_ptr只是一个GET /重置智能指针？

--------------解决方案-------------

A unique_ptr is also known as std::unique_ptr. Before C++11 it was boost::unique_ptr, but became a part of STD library in C++11 and is now called std::unique_ptr.

A scoped_ptr is generally known as boost::scoped_ptr, and is from the “ancient” ages before C++11 came along with the header with std::unique_ptr (and std::shared_ptr). Note that there is NO such thing as std::scoped_ptr! Only boost::scoped_ptr and std::unique_ptr. Generally, its std::unique_ptr you should use.

If you’ve been using boost, and have any scoped_ptr lying around, you can (almost always) safely replace them with std::unique_ptr. There are a few subtle differences between scoped_ptr and unique_ptr, but they are mostly an artifact on how “old” they are.

	boost::scoped_ptr	const std::unique_ptr
Copyable	No	No
Movable	No	Yes

If you want to disallow moving with std::unique_ptr, use const std::unique_ptr.
