In Windows, it is implemented through a data structure called NetBufferList,
the data in the form of NetBufferList passes different layers of networking
stack, each layer makes some modification but the original payload is not

手上正好有50多张receipt要copy，就准备顺路去copy.
一问，原来：
1.外面随便用的copier 要必须插credit card后才能用，这样就收了钱了，不能
用coupon了。
2. 那就用copy center里面的吧。一定要copy 100或100张以上才能用这个coupon。
---好吧，就浪费你丫的纸，我一张收据复印两张行不行？
3. copy center里面不让我进去，必须由他们的工作人员来动手。
收据小票不能放在auto feeder，必须要放flatbed里面copy，
因为他们付出劳动和汗水了，所以必须每张付20cents，这个不能用coupon减。
你妹的，我还不如直接付10cent一张自己复印？这样的coupon有什么鸟意思？ |

所谓certified copy，意思是说内容由发证机构核实无误的，比一般true copy更可信
。ture copy只是说copy是真的，但原件的内容是否真实，甚至原件是否伪造，公证员
并不能做出准确判断。
鉴于这个原因，除非护照是休斯顿领馆签发的，休斯顿领馆即使想做也根本没有办法做

}

{

obj.namedObj(); //这个就不会调用copy constructor

为什么会有这个区别呢？ 不是说只要返回值不是reference 就会copy么？
