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

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

UNIX advanced environment programming (13) signal, unix programming 13 Signal The signal is Soft Interrupt. Signals provide an asynchronous way to process events. For example, you can press the End Process key on the terminal to terminate a process
