Linux signal Programming Practice (2) signal sending function and reentrant function In the early UNIX era, the signal was unreliable. It cannot be said that the signal may be lost, but a signal may occur, but the process may never know this. Currently, Linux calls unreliable signals before the SIGRTMIN real-time signal. The unreliable signal here is mainly because the signal queue is not supported, that i
