- readn, writen and readline functions in Linux network programming: how to read and write byte streams efficiently
- In Linux network programming, we often need to use byte stream sockets to transmit and receive data. However, when calling the read and write functions on a byte stream socket, the number of bytes input or output may be less than the requested number, because the buffer in the kernel for the socket is limited, requiring the caller to Call the read or write function several times. This will increase the complexity of programming and the possibility of errors. In order to solve this problem, we can use some encapsulated functions to implement fixed-length or line-by-line reading and writing functions. These functions are readn, writen and readline functions. This article will introduce the functions, principles, implementation and usage of these functions to help you improve Linux network programming.

- Use TC to elegantly implement network current limiting under Linux
- 1. Principle of flow control under Linux We can control the way data packets are sent by queuing them. This kind of control is called data shaping, which means performing the following operations on the data: Adding delays Dropping packets Rearranging duplicates or corruption Controlling the rate Under the qdisc-class-filter structure, three steps are required to control traffic: Create a qdisc queue Since Linux controls traffic by queuing packets, you first need a queue. Creating a class class is actually used to classify traffic policies. For example, two traffic speed limit levels can be divided: 10MBps and 20MBps. Create filter even though class has already been created

- Dual-core CPU killer makes your Linux process run faster!
- When using Linux systems, we often encounter some CPU-intensive tasks, such as data processing, compiling programs, etc., which require a large amount of computing resources to complete. However, if our system hardware configuration is low, it will cause slow task execution and seriously affect our work efficiency. To address this problem, this article will introduce a technology called "CPU binding", which can bind a process to a specific CPU core, thereby improving the execution efficiency of the process. For ordinary applications, the default scheduling mechanism of the operating system is no problem. However, when a process requires higher operating efficiency, it is necessary to consider binding it to a separate core to reduce the overhead caused by scheduling on different cores. Put a process/thread

- Format text using Linux fmt
- The fmt command is a simple text formatter. I'll show you how to use it here to format text and email responses. When I write documentation for a project, I often write readme files and installation instructions in plain text. I don't need to use a markup language like HTML or Markdown to describe what the project does or how to compile it. But maintaining such documentation can be a pain. If I need to update the middle of a sentence in my Readme file, I need to reformat the text to avoid having a long or short line in the middle of my other text, which is neatly formatted Qi 75 columns. Some editors include features that automatically reformat text to fill paragraphs, but not all editors
