This document describes how to create an ADO. Net object data model through EF4. The tool used is Visual Studio 2010 beta 2, which may be different from the final release. Later articles will explain how to use EP4 to query and display data, call the stored procedure, and customize the classes generated by EF4.

3. Become the ancestor of the rich. Life is regarded as a hero, and death is also a ghost hero. Every day, we are doing our best to get things done. It hurts us to buy all kinds of household appliances. Isn't this life suffocating? Why not strive hard to realize your own value. It's not sad that you don't own it every day. Sadly, you don't want to own it. The greatest tragedy of life is the disappearance of dreams and the depletion of life.

the two pointer variables subtract, the pointer variables must be of the same type, as shown in figure
Int I = 0x0f30348a;
Char * pch = (char *) ( I );
Char * pch2 = pch + 1;
Int iEleCount = pch2-pch;
Adding the two pointers has no practical significance.The comparison of the two pointers indicates the comparison of the addresses of the variables pointed to by the two pointers. The two pointers must be of the same type. For example
Char c
This can also be done through the cyclic shift operation:
MoV Al, 12 h; original data in Al
MoV CX, 8; Al, byte type, total 8 bits
MoV ah, 0; Ah is used as the intermediate register for transposition. The initial value is 0.

SHL Al, 1; shifts 1 to the left, and the current highest bit enters cf
RCR ah, 1; Ah shifts 1

Any mutex Protocol has the following problem: If the lock cannot be obtained, what should we do? There are two options for this. One solution is to let it continue to try. This lock is calledSpin lockThe repeated lock test process is calledRotating or waiting. It is reasonable to select the rotation method when the lock delay is short. However, only rotating in a multi-processor has practical significance.

Ext4 does not explain what ext4 is. It can read thisArticleYou must know.
Download the ext4 compressed package, dozens of megabytes a day. This is not written by humans.
But what I want to say is: the author intentionally makes it so big that there is not so much single source code, about 3 MB.
It is not easy to interpret the source code of Ext.
But I believe many people need it!
I hope this source code explanation will benefit you a lot.
Of course, if you don't even know the basic J
1. Pointer conceptThe address of the variable is called the pointer of the variable, and the variable storing the pointer is called the pointer variable.A pointer variable is a variable that stores the address values of other variables. For exampleInt I;Int * pi = I;The pi variable value is the address of variable I.* Is added before the pointer to indicate the memory unit pointed to by the pointer. For exampleInt I, j;Int * pi;Pi = I;I = 9;J = * pi
