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

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 of Linux programming, this article will detail the basic concept of signal mechanism, the approximate realization method of Linux to signal mechanism, how to use signal, and several system calls about signal.Signal
