linux signal 13

Signal is a very important part in Linux programming. This article will introduce in detail the basic concepts of the signal mechanism, the general implementation of the signal mechanism in Linux, and how to use the signal, and several system calls

A signal (signal) is a software interrupt that provides a way to handle asynchronous events and is the only asynchronous communication between processes. In a Linux system, the subsequent signaling mechanism is extended according to the POSIX

Signal is a very important part in Linux programming. This article will introduce in detail the basic concepts of the signal mechanism, the general implementation of the signal mechanism in Linux, and how to use the signal, and several system calls

A signal is a software interrupt, an asynchronous communication method that handles an asynchronous event. For example, we run the program in the terminal, by pressing the keyboard "CTRL + C", you can send a SIGINT interrupt signal to stop the

signal and its processing signal processing is an event that UNIX and Linux systems generate in response to certain conditions, usually the kernel generates a signal, and the process receives a signal and takes action accordingly .For example,

First of all thank you Liao brother this friend to me last night wrote a "talk about the signal mechanism of Linux (a)", before the topic I used the word "analysis", give a person to analyze the feeling of the kernel. I know the skill is not enough,

For a complete signal Life Cycle (after the signal is sent to the corresponding processing function for execution), it can be divided into three phases: Signal Generation Sign up in process Logout of signal in process Signal processing

In Linux, a signal is a way of communicating between processes, and it uses an asynchronous mechanism. When the signal is sent to a process, the operating system interrupts the normal process of the process and enters the appropriate signal handler
