linux signal handler

First, signal and signal sourceSignal EssenceThe signal is a simulation of the interrupt mechanism at the software level, in principle, a process receives a signal that the processor receives an interrupt request can be said to be the same. The

Core Signal Processing Reference:Http://www.spongeliu.com/165.htmlThe signal is essentially a simulation of the interrupt mechanism at the software level (attention to distinguish interrupts, anomalies, signals), which mainly have the following

Http://blog.chinaunix.net/uid-9354-id-2425031.htmlSo I hope that the same way to deal with the multiple occurrences of the signal, it is best to use sigaction. The signal only appears and is processed once, can be used signal.Each time the signal

The linux signal mechanism is far more complex than imagined. This article strives to use the shortest length to make in-depth and meticulous analysis on the machine. You can read the signal application instance (in the signal (below) first, so that

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

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
