Emphasize one point:
#pragma packs (4)

{
Char buf[3];
Word A;
}KK;
#pragma pack ()
The principle of alignment is min (sizeof (word), 4) = 2, so it's 2-byte alignment, not the 4-byte alignment we think.
Here are three important points:1. Each member is aligned in its own way and can minimize the length of2. The default alignment of a complex type, such as a struct, i

Problem description
We often add expansion packs to existing projects, sometimes because of incorrect documentation, such as from this document:
Composer Update This command may cause significant damage to the project in our current logic.
Because the logic of composer update is to update all expansion packs to the latest version with the extension package version rules specified by Composer.json, note
:
Copy Code code as follows:
#pragma packs (8)
struct S1
{
Short A;
Long B;
};
struct S2
{
char c;
S1 D;
Long long E;
};
#pragma pack ()
There is an important condition for member alignment: Each member is aligned separately. That is, each member is aligned in its own way.
This means that although the above specifies a 8-byte alignment, not all members are aligned in 8 bytes. The rule for its alignment i
examples of detailed instructions.The compiler I'm experimenting with is GCC 4.4.6
We will use a typical struct to explain. First we define a struct:#pragma pack (n)/* n = 1, 2, 4, 8, 16 * *struct TEST_T {int A;Char b;Short C;Char D;};#pragma pack (n)First, we first identify the size of each type on the test platform, and verify that the output of the two compilers is:sizeof (char) = 1sizeof (short) = 2sizeof (int) = 4
Our trial process is as follows: Change the "alignment factor" by #pragma pa
secure as possible. Windows NT is complex enough to use a book to talk about security, but with limited space, you just need to remember a few questions.First, make sure that all the disks associated with the Exchange files are in NTFS format and that many hackers try to attack NT servers and access the system through a network share, although you cannot block network sharing, but remember that file permissions (specified by NTFS) bring additional security to the server. Windows NT uses more re

Q: My husband I are considering the four day hike in November. I 'd like to hear from those who have done this. What is the lodging like? Do we have to bring sleeping bags, etc? What about food? Sounds like it rains a lot so what is the hiking like? Muddy? Good footing? We enjoy hiking but haven't really done backpacking so I'm trying to find out what the logistics are. A: Hi Shera-

In the work, you may encounter the need to migrate the code written in VB to VB. NET, there are a lot of details to deal. Fortunately, after so many years of Internet development, many questions have been answered on the Internet, so you can search for them to solve them. I have also encountered the migration from VB to VB. NET. Now I will summarize the problems encountered and their solutions or alternative methods to facilitate future users.
