linux signal numbers

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

The basic series is better than the subsystem series. Most of these series are excerpted. Many brothers have made a good conclusion before and thank you for choosing them. I have recently dealt with a debugging problem involving Linux signals. I

SignalIs the oldest process communication method used by UNIX systems. Signals can not only be sent from the kernel to one process, but also from one process to another. For example, if you start a program that needs to run for a long time in the

Signal (signals)A signal is a soft interrupt and is a method of handling asynchronous events. In general, the operating system supports many signals. In particular, UNIX, a more important application typically processes signals. UNIX defines a

  Signal, an event notification that the OS sends to proc. Each signal corresponds to a system event. The signal is transmitted to proc, Which is captured and executed when the kernel state is switched back to the user State. The specific execution
