[go-nuts] is there a goroutine scope global veriable ?

[hui zhang]

I write logs into one single log file.
and need to set a different tracking id for each goroutine.
But I don't want to pass the tracking id argument for all functions.


func main() {
  go Func()
}
func Func() {
  SetLogTrackId("xxxx")
  LogDebug("123")
  call1()
}
func call1() {
   LogDebug("call1")
}
var trackId string //need this scope to be goroutine scope
func SetLogTrackId(id string) {
    trackId = id
}
func LogDebug(v ...interface{}) {
    log.Println("DEBUG " + trackId + " " + fmt.Sprintln(v...))
}
