What should I pay attention to when writing a word?

In the past, a pppoe protocol was built on a single tablet. The number of messages sent was always one more word, which caused the loss of the seller. When a packet is captured, the font still changes... Later, I thought that the tablet was a 16-bit device, and the words of the volume-based phone were reserved, A one-character hole exists in the structure. When the packet is sent, the empty hole is also sent out, and then changed to a one-character box to solve the problem.

This is a meaningful experience. We can see in our latest RFC that most of our suggestions are directed to each other by 4 characters. This is not a problem in 32-bit systems. We don't seem to have to care about this issue. However, we may not be able to press the 4-character phrase for each other. Now the 64-bit hardware Street is full, in the past, many of my anti-bot multi-media files were found to have 16-character comparison. Therefore, when dealing with the network data, it is best to explain one or more images. The default configuration may change without any experience. You still cannot figure out the problem.

For example, in VC, you only need to add the statement that shows 1-character pairs of zookeeper commands before and after the component description, the other parts are still matched in the original method, for example, there is a structure A, in the header file test. h,

 

Test. h

---------------------

...

# Pragma pack (1) // sort the cursor by one word

Struct

{

Char M1;

Int m2;

Char m3;

}

# Pragma pack () // Restore original Pair Mode

...

 

In test. C, when a type A change is declared, it will automatically create the change in a way that corresponds to each other.

Test. c

-----------------

Struct stxx; // The structure consists of six characters, where the # pragma pack command does not need to be used.

 

Check the inner memory under VC.
