What's your code?

[rajkumarks7]

I can share you somepart of code

[rajkumarks7]

Package main func main() {

go Mousecount()

}

func Mousecount() {
for {

    EvChan := hook.Start()
    defer hook.End()

    var j uint16
    b := 0
start:=time.now()
    for ev := range EvChan {
        fmt.Sprint("hook: ", ev)
        j = j + ev.Clicks
        if ev.Rawcode >= 1 {

            b++

        }
        if time.Since(start) > time.Second*59 {

            break
        }
    }

    fmt.Println(j / 4)
    fmt.Println(b / 4)

    time.Sleep(500 * time.Millisecond)
}

}

Have you tried putting select{} after go Mousecount() (to pause until kill/TERM). Your program will exit instantly otherwise

[rajkumarks7]

No I did not can you tell me where do I use it ? In my code I do have other go routines

i used like this func main(){ go Screenshots() go mousecount() select{} } but i am still getting this error

[skuzzymiglet]

Have you tried obtaining the event channel and then passing it to both?

[rajkumarks7]

No I did not can you tell me how to do it ?

[skuzzymiglet]

Do:

EvChan := hook.Start()
defer hook.End()

in main().

Modify the functions to take a chan hook.Event as a parameter. Then range over that parameter

[rajkumarks7]

Okay I should try with it then thank you

EvChan := hook.Start()
defer hook.End()

hey can you show me once i am not getting it
