InnoDB summarizes four different Search modes for different SQL statements:
# Define PAGE_CUR_G 1> query
# Define PAGE_CUR_GE 2 >=, = query
# Define PAGE_CUR_L 3
# Define PAGE_CUR_LE 4
Then, based on the four different Search modes, adjust the Search Mode when the binary Search encounters the same key value. For example, if the Search Mode is PAGE_CUR_G or PAGE_CUR_LE, move low to mid and continue the binary Search. if the Search Mode is PAGE_CUR_GE or PAGE_CUR_L, move high to mid

In this simple way, if you need to understand the annotation in depth, you can check the annotation information.About the injection framework, you should know everything to build your own injection framework.

Automatic summary is summarized to 172.16.0.0/16
If you are manual, you are happy to summarize where it is, and where it is, just as needed!
For example, you can aggregate the data to 172.16.0.0/20 or 172.0.0.0/8.
For example, if the ISP gives tnt a 210.231.223.0/24 network, if it is hidden by default, it is/24, then there is only one network segment and there are only 254 addresses, then in a practical application,
After I went to work on November 3.19, I found that the boot speed of my computer had changed from 40 seconds to 4 minutes, but I did not change my computer.

I found a QQ number for 360 beautiful women. I consulted, as a result, we will share with you the solution:

I have written a program to intercept MessageBoxW, you can see, maybe some help for you.
The program is based on the principle of hook, mainly to put their own functions in the target process address space, here is the use of hook implementation. First set up a mouse hook program, and then in the global mouse hook DLL in the Intercept action, you can Process_ When attach, you can also do it in the hook chain function of the mouse.
Set up a global hook I will not say, can be seen in many places
