/B stream... what should I do? For a long time, I always thought that I was wrong, Google, Baidu, and no result. As a mature iptables that has been used for so long, it will not make mistakes. It must be my mistake. So my next plan is to find out: What is wrong with me?This is just a comfort. In fact, I know that I am not wrong. Simply put, reply represents the meaning of return. My actual plan should be to find evidence that I was not wrong. I have been searching for this evidence on the Intern

Easy to call services. Here is an example. For example, if I have an API for sending text messages, which is provided by a third party, how can I package it?
The following code and description of API encapsulation are provided.

SNAT, Dnat objective function
The Ip_nat_rule_find () called in the IP_NAT_FN () function is used to find the NAT rules, perform the action of the rules, and the rule target is either Snat or Dnat, which is specifically implemented in Net/ipv4/netfilter/ip_nat_ In rule.c.
Either Snat or Dnat rules, the goal function is ultimately to call the Ip_nat_setup_info () function to establish the connection's NAT info.

First, make it clear:
If (likely (value) is equivalent to If (value)
If (unlikely (value) is also equivalent to If (value)
That is to say, likely () and unlikely () are the same from the perspective of reading and understanding the code !!!
These two macros are defined in the kernel as follows:
# Define likely (x) _ builtin_exact CT (x), 1)
# Define unlikely (x) _ builtin_exact CT (x), 0)

Although we can:
Int x = 1;
If (x = 0 ){
Console. WriteLine ("Regular member ");
} Else if (x = 1 ){
Console. WriteLine ("VIP member ");
}
But for fear, the x variable is declared too early, and some operations occur during the period, resulting in a change in the result. In case of calculation, x = 5; in this case, how can I display the membership type? Although this phenomenon rarely happens, it
, Tcl is also known as the "glue" language. It is highly cohesive! If Python does not provide the function provided by library files, you can use the C language to implement this function and then integrate it. The same is true for Tcl. One important feature of Tcl is its scalability. If a program needs to use some functions not provided by the standard Tcl, you can use the C language to create some new Tcl commands and integrate them easily. Tk is a series of commands and processes that make Tc
