A signal is a software interrupt, an asynchronous communication method that handles an asynchronous event. For example, we run the program in the terminal, by pressing the keyboard "CTRL + C", you can send a SIGINT interrupt signal to stop the

The trap command is used to specify the action to be taken after the signal is received. A common use is to complete the cleanup when the script is interrupted. However, this time I met it because the customer has a requirement: the user who

Signal System Function calls provide a simple example. However, the C prototype Declaration makes it look more complex than the actual one. The signal function associates a given function with a specific signal. Here is the definition in FreeBSD
