C++ Rvalue Reference的一些链接的记载

好文推荐与摘录：

http://www.cprogramming.com/c++11/rvalue-references-and-move-semantics-in-c++11.html

关于C++ Rvalue Reference 和 std::move() 的讲解. 讲解得非常透彻，真可谓“循循善诱”。

1 string getName ()
2 {
3     return "Alex";
4 }
5 getName();
6 
7 
8 const string& name = getName(); // ok
9 string& name = getName(); // NOT ok

 
"holding on to a const reference to a temporary object ensures that the temporary object isn't immediately destructed. This is a nice guarantee of C++, but it is still a temporary object, so you don't want to modify it"
 
"both lvalue and rvalue references are lvalue expressions"
 
"std::move does not, in and of itself, move anything; it just turns an lvalue into an rvalue, so that you can invoke the move constructor."
"You might be wondering, how does one write a function like std::move? How do you get this magical property of transforming an lvalue into an rvalue reference? The answer, as you might guess, is typecastin . The actual declaration for std::move is somewhat more involved, but at its heart, it's just a static_cast to an rvalue reference."
 
有一个地方貌似有点错误，就是
Returning an explicit rvalue-reference from a function这一段
On the other hand,

1 printAddress( getRvalueInt() );
2 printAddress( x );
prints the same value because we are explicitly returning an rvalue here.
应该改成：
On the other hand,

1 printAddress( getRvalueInt() );
2 printAddress( x );
prints the same value because we are explicitly returning an rvalue reference here.
(少了一个reference)
       我一直认为，一个人如果对某些知识有了真真正正的理解，而且愿意写（讲），那么写（讲）出来的就一定是像这种文章一样的 “循循善诱” 式
的“深入剖析”。因为如果真的很了解，那么就一定会知道一个知识点的关键所在，知道这个东西的细微之处，和与其他东西的本质区别，也就可以
讲好，讲懂，而不是列出一堆别人不知所云，自己也不一定完全清楚的东西。
       而且，这种细致入微的剖析，其实也是对自己知识体系的一种重建，通过这个过程，自己也会对那一知识有更深入的了解。
       不过嘛，写起来确实挺麻烦的，还要考虑排版（有时候还要画讲解图），所以有时候就只能去头去尾了......
