When writing a socket program in Linux, if you try to send it to a disconnected socket, the underlying layer will throw a sigpipe signal.
After the client sends a message to the server through pipe, it closes the client. At this time, the server generates a broken pipe signal when it returns the message to the client.
For signal generation, we can use the method signal (int signum, sighandler_t handler) before signal generation)Set signal processing.

Broken Link

The 10 thousand forbidden (World Wide Web) link points to an invalid page. When the link cannot be found, the server usually returns
Error 404
.
There are two causes for dead links:
1. It may be that the Domain Name of the server cannot be resolved, or the link cannot be accessed due to content filtering measures or firewall blocking.
2. The Link error occurs when the website content is updated, chan
the screen is displayed, call can be, but the screen light is very dark or not bright. Cause: LCD lights are powered in series, and the motherboard supplies 18 V for screen lights, which is the highest voltage on the motherboard, if the motherboard is slightly wet, the working environment humidity is high, or there is static electricity, it may cause the screen lamp boost chip to burn out, resulting in the screen lamp is not on. Solution: Change the screen lamp to boost the chip5. Why iPhone 4
Question:
Simulate a text editor. You can enter letters, numbers, and underscores (_). If '[' is used, it is considered as the Home key. If it is set to ']', it is used as the end key.
Ask what string is displayed on the final screen.
Analysis:
It is time-consuming to move a large number of characters in an array. Therefore, the next array indicates the character number on the Right of S [I] in the display. The variable cur simulates the cursor, that is, the current cursor is located on the righ
A senior executive of Microsoft recently said that it is an absurd idea to regard Linux as a security platform, according to a report from the Internet on September January 30. In fact, the development form and process of the Linux operating system just buy security risks.
Nick McGrath, head of the platform strategy department of Microsoft UK, said in an exclusive interview with vnunet.com that the "Security myth" of the Linux operating system will soon be
I have been using a tplink router. After receiving a project, this Organization has no network management service. I think tplink is generally a low-end product. dlink is a high-end product in the industry. Will it be better? The network is unstable in the future, so I recommended this company to buy this broken di7200. But I don't know what the nightmare is. At the beginning, many websites won't be able to get connected. I think I have encountered th

establishment of the link, but nothing can be. Then such a link is empty connection, wasted bandwidth.TCP VS UDPFirst say the same point, both of them can be full duplex, and are end-to-end Transport Layer communication protocol.TCP is generally used for file transfer, because the file transmission requirements are true, shred can not be less, so every time the establishment must require that the data are perfect.TCP is only one-to-many, does not support broadcast and multicast, and TCP is byte
fin_wait_1. When the client process host is running to receive an ACK acknowledgement, the connection in one Direction is closed. The state becomes fin_wait_2. When the host running the client process receives a message that the host that is running the server process sends a FIN of 1, it should respond with the acknowledgment ACK, which is another connection shutdown. At this point, however, TCP waits for a period of time before deleting the original established connection record. Returns to t
full of hardships, at first I did not contact MySQL for a while, and then open the statement should be mysql-uroot-p, but I wrote the MySQL uroot-p, so I entered the password after the 10045 error, to search the Internet solution , but a lot of people say that MySQL is not installed, and finally I found a solution, that is I looked at the blog before I wrote the garden, I saw the command line, suddenly, or very happy, MySQL does not have to reinstall.3.
