Mastering Go - Second Edition

Handling two signals

In this subsection, you will learn how to handle two signals in a Go program using the code found in handleTwo.go, which will be presented in four parts. The signals that will be handled by handleTwo.go are SIGINFO and SIGINT, which in Go are named syscall.SIGINFO and os.Interrupt, respectively.

If you look at the documentation of the os package, you will find that the only two signals that are guaranteed to be present on all systems are syscall.SIGKILL and syscall.SIGINT, which in Go are also defined as os.Kill and os.Interrupt, respectively.

The first part of handleTwo.go contains the following Go code:

package main 
 
import ( 
    "fmt" 
    "os" 
    "os/signal" 
    "syscall" 
    "time" 
) 

The second part of the handleTwo.go program follows: ...
