sigint signal number

The signal is associated with a certain process. In other words, a process can determine which signals are handled in the process. For example, a process can ignore some signals and handle only some other signals, and a process can also choose how

1. Signal ConceptA signal is a message (event) that is generated by itself or sent by the process outside the process during its operation. The signal is a hardware interrupt software simulation (soft interrupt). Each signal is represented by an

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
