Both Windows and Linux support zero-copy in kernel networking stack.
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
copied (so this is called zero-copy). Finally networking device driver copy
the payload inside NetBufferList to onboard buffer of network adapter and
then network adapter send the data.

来自主题: JobHunting版 - 这个copy random link真不容易写对
好吧,我写个copy random graph的通解,对一切graph,tree,list什么的都有效。
区别是O(n)space 复杂度。可以拿来救场。
标准list copy应该是O(n) time, O(1) space.
假设hash class, equal class已经定义好了。

请问各位一个州税相关的问题:
我的公司给我的W-2中, 总共有三份copy(就是W-2下部那些小纸条),
其中,一份注明给federal(注明Copy B), 另外两份给state(注明Copy 2)
我的这两份Copy 2, 一份是" State reference copy" ,另一份是" State Filing Copy
", 两份的底部都注明了"Copy 2 to be filed with employee's State Income

如果你有兴趣的话,请站内短信联系我。因为copy的时间很长,而且多次copy的话,对
硬盘磨损也大。看看有多少人有兴趣,我将汇总整个名单(大致按照先来后到和地域远

来自主题: ebiz版 - staples的copy center真搞笑
昨天翻出了大半年前staples寄给我的coupon, 100张free B&W copy。
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?

中国护照true copy不敢说休斯顿领馆每天都在做,但至少每周会有几个。
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

assignment operator exists
* When the class is derived from a base class for which a copy

* When the class declares one or more virtual functions (we must not

关于什么时候调用copy constructor的问题, 看下面的例子
class cType
{
public:
cType(){}
cType(const cType& obj)
{
cout << "copy constructor is called" << endl;
}

cType namedObj()
{
cType d;
return d;
}
cType pointer()
{
cType *d = new cType();
return *d;
}
};
int main()
{
cType obj;
obj.namedObj(); //这个就不会调用copy constructor
obj.pointer(); //这个就会调用 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?

It is required by USCIS to send the original copy. Check the material list
included in the I539 form instruction.
However, many sent duplicated copy and succeeded in transference while I know
some guys were asked to resend the original copies and thus delayed case
processing.
In case that it would happen, I sent the original copy and got it back intact
after approval.
