  1.4 错误处理:包裹函数 既然发生错误时终止程序的运行是普遍的情况,我们可以定义包裹函数(wrapper function)来简化我们的程序。包裹函数调用实际函数,检查返回值,并在发生错误时终止进程。 int Socket(int family, int type, int protocol) { int n; if ( (n = socket(family, type, protocol)) < 0) err_sys("socket error"); return(n); } (更多)

  第4.4章 bind Function 有一段话不怎么明白，原文如下： We must be careful to distinguish between the interface on which a packet arrives versus the destination IP address of that packet. 下面还提到在8.8节会讲到week end system model和strong end system model, but I didn't find that in 8.8 section, why? and more: it is okay for a packet to arrive with a destination IP address that identifies an ...

  下面还提到在8.8节会讲到week end system model和strong end system model, but I didn't find that in 8.8 section, why?

  and more:

  it is okay for a packet to arrive with a destination IP address that identifies an interface other than the interface on which the packet arrives. (收起)
