When a thread calls a function fork, the entire process address space is copied to the child process, Copy-on-write is mentioned in section 8.3. A child process is a process that is completely different from the parent process, but if neither the

For Windows, the concepts of processes and threads are clearly defined, and the concept of a process corresponds to a running instance of a program (instance), while a thread is the smallest unit of execution of a program's code. This means that

1. Each thread has its own signal screen word2. Each thread shares a signal processing function for the same signal.3. After the main thread is set Pthread_sigmask, the sub-thread will copy a set of signal screen words.Then we'll look at the

1. Experiment 1: Signal Communication description: use signal communication to communicate between parent and child processes and brother processes. solution: Send a SIGCHLD signal to the parent process at the end of the sub-process, the parent

I. Inter-process communication overview process communication has the following purposes: A. data transmission: A process needs to send its data to another process, the sent data volume is between one byte and several MB. B. shared data: if multiple

Article title: Proxy Source Code Analysis-talk about how to learn linux network programming. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research,

Today, we can see that there are fork sub-processes in others' source code to operate data. However, as fork does not exit in time, the number of Python processes in the system increases and the number of sub-processes increases. I wrote the test

There are some backdoors in many protocol applications. For example, the Linux ICMP backdoor we will introduce today. Next, let's take a detailed look at the specific content about the 137-byte remote ICMP backdoor in Linux. Use the Ping Control

Tiny Web server code analysis A small but fully functional web server called Tiny has been developed in "deep understanding of computer systems". Here is the source code parsing of the Tiny server. 1. Tiny main program Tiny is an iterative server

When implementing CGI programs, we sometimes use setenv to set environment variables and pass them to sub-processes. How is the parent process passed to the child process?[Cpp]// Father. c# Include # Include # Include # Include # Include  Extern

The hard disk Of A redis machine was full the other day, mainly because of program bugs that led to a surge in backup volume, and the monitoring program's notification mechanism also went on strike, so for the first time, I experienced the redis

Fork under linux-general Linux technology-Linux programming and kernel information, the following is a detailed description. In linux, fork generates a sub-process, called once, and returned twice. Fork () Fork () = 0, in the sub-process.

1 , the first thing to clarify is the meaning of the process and thread:Process is a program with a certain independent function on a data set on a running activity, is the system for resource allocation and scheduling of an independent unit.
