使用golang在Windows和Linux中捕获ctrl + c或任何其他进程终止信号

I am trying to build a chatroom application in go and I want to call logout function when client uses ctrl+c or presses close buttom of the terminal.
I tried methods given here and here but they were not capturing any signals(tried in Windows 10 and Fedora 23). Here is my code snippet,

sigc := make(chan os.Signal, 1)
signal.Notify(sigc,
    syscall.SIGHUP,
    syscall.SIGINT,
    syscall.SIGTERM,
    syscall.SIGQUIT)
go func() {
    _ = <-sigc
    fmt.Println("ctrl+c pressed")
    client.Logout()
}()

I have some other functions running concurrently using goroutine, is it the reason behind this function not capturing any signals?

Any help would be appreciated.

According to the docs on os.Signal, it should be possible to catch interrupts on Windows: https://golang.org/pkg/os/signal/#hdr-Windows. I haven't tested this personally, though.

I suspect your problem is that you should only use signals imported from os, such as os.Interrupt, instead of syscall.

From https://golang.org/pkg/os/#Signal:

The only signal values guaranteed to be present on all systems are Interrupt (send the process an interrupt) and Kill (force the process to exit).

And from https://golang.org/pkg/syscall/#pkg-overview:

The primary use of syscall is inside other packages that provide a more portable interface to the system, such as "os", "time" and "net". Use those packages rather than this one if you can.

So, change your signal.Notify call to catch only the os.Interrupt signal.
