[go-nuts] How to set a callback for cgo ?

[astone . chou]

Hi everyone,

I want to set a callback for atexit, but it seems doesn't work. 

This is my code.

package main

/*
#include <stdlib.h>

extern void AtExit();

static inline set_atexit() {
    atexit(AtExit);
    AtExit();
}
*/
import "C" 

import (
    "fmt"
    "io/ioutil"
    "time"
)

var n = 0 

//export AtExit
func AtExit() {
    ioutil.WriteFile(fmt.Sprintf("exit%d", n), []byte("yes, exit 
success\n"), 0644)
    n++ 
}

func main() {
    C.set_atexit()
    fmt.Println("call set_atexit")
}

I get the file 'exit0', but didn't get the file 'exit1'.

Best regards,
Astone
