First on the code:
var data *stringP: = (*string) (Atomic. Loadpointer (*unsafe. Pointer) (unsafe. Pointer (data))
There are two questions to discuss:
Unsafe. Pointer and *unsafe. can pointer be converted directly?Answer: You can convert.Depending on the test, the result is:(unsafe.Pointer) 0xc42000e0a8(*unsafe.Pointer)(0xc42000e0a8)(0xc4200115f8) // 0xc4200115f8为data实际地址

less fun. But it rarely works.
it is not object-oriented or has any defects. But object-oriented is not the basic atom of computer programming, they do not exist naturally as people imagine. Using object-oriented to solve the problem without a threshold will make the code bloated and over-Technical. However, many people insist on persistently using objects to solve all the problems. This is terrible because it makes it difficult for people to ident

Question:
① In the implementation of atom_new, why not use strncmp to compare newly added strings with existing strings?
② "Atom
1. Introduction
Atom is intended to be "the smallest particle that cannot be further divided", and atomic operation is "one or more operations that cannot be interrupted ". It is a little complicated to implement atomic operations on a multi-processor. In this article, let's talk about how the Intel processor and Java implement atomic operations.2. Definition of Terms

formula (refresh time formula):
TWWDG = T_max-t_min
= 4096 * (2^WDGTB) * (wwdg_cfr[6:0]-0x3F)/36 (US)
= 4096 * (2^WDGTB) * (wwdg_cfr[6:0)-/36 (US)
And because wwdg_cfr[6:0] value range is: 0~127,
(wwdg_cfr[6:0]–63) >0,
So
1
And because a 6-bit binary x[5:0] value range is 0~63,
1
So
The above formula can be expressed as:
TWWDG = 4096 * (2^WDGTB) * (t[5:0]+1)/36 (US)
(4) According to the above formula, can calculate the timing range of WWDG:
WDGTB (counter divider value)

Here's how to get this effect.
1. Enter Atom's setup interface. Select the plug-in.
2. Find the plugin we need. It's called "Activate-power-mode."But because it is very hot, so say that most of the first is it, if it is not the case of the
