SignalIs the oldest process communication method used by UNIX systems. Signals can not only be sent from the kernel to one process, but also from one process to another. For example, if you start a program that needs to run for a long time in the

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
