  Signal, an event notification that the OS sends to proc. Each signal corresponds to a system event. The signal is transmitted to proc, Which is captured and executed when the kernel state is switched back to the user State. The specific execution

In signal (I), we discuss linux signal types, sources, how to install a signal, and how to operate the signal set. This section first discusses how to understand the signal from the signal life cycle, or a seemingly simple signal mechanism at a

In Linux, how does one kill a process ?, Linuxkill Linux Command lines are used to stop all required tools for running processes. Imagine: You opened a program (probably from your desktop menu or command line) and started to use it. I didn't expect

interprocess communication (Ipc:inner proceeding communication)A process is a way for an operating system to implement an illusion of exclusive system execution. is an abstract representation of the processor, main memory, I/O devices. Each process

In the case of the Tcpserv service program:1) Parent Process: Responsible for system initialization, as well as listening (listen), accepting connection request (accept), where accept default blocking call.2) Each receive a connection request,

1, in order to track and describe the process from generation to extinction, it is necessary to define various states of various processes and formulate corresponding state transition strategies to control the operation of the process.Different
