How to determine that the program will be stopped?

[heretic13]

Hello.

There is a console program. How do I intercept the event of closure and perform some action on the freeing of resources?

Interception SIGINT does not work.

Messages from log:
2016-05-29 11:27:56 - Send SIGINT 8368
2016-05-29 11:27:56 - SIGINT to 8368 failed - Killing as fallback

I think problem in 'AttachConsole'.

OS: Windows 10 x64

Relly simple code in go to test it

---

package main

import (
"fmt"
"os"
"os/signal"
)

func main() {
// Set up channel on which to send signal notifications.
// We must use a buffered channel or risk missing the signal
// if we're not ready to receive when the signal is sent.
c := make(chan os.Signal, 1)
signal.Notify(c, os.Interrupt)
// Block until a signal is received.
s := <-c
fmt.Println("Got signal:", s)
}

It works when yourself push Ctrl-C, but I do not see a message about closing when working through the wrapper

Modify program

package main

import (
"fmt"
"io/ioutil"
"os"
"os/signal"
)

func main() {
fmt.Println("hello")
// Set up channel on which to send signal notifications.
// We must use a buffered channel or risk missing the signal
// if we're not ready to receive when the signal is sent.
c := make(chan os.Signal, 1)
signal.Notify(c, os.Interrupt)
// Block until a signal is received.
s := <-c
fmt.Println("Got signal:", s)
d1 := []byte("hello\ngo\n")
ioutil.WriteFile("dat1", d1, 0644)
}

Most likely it's a Windows service specifics.
Need to RTFM about the signal handling behavior in this case.
