After running a rather simple Go program:
package main
import (
"fmt"
"os"
"os/signal"
"syscall"
)
func main() {
sigs := make(chan os.Signal)
signal.Notify(sigs, syscall.SIGINT, syscall.SIGTERM)
fmt.Printf("awaiting signal at %d
", os.Getpid())
<-sigs
fmt.Printf("
exiting
")
}
I can observe the following threads being created on my system (found by top -H to list threads aside processes):
3949 USER 20 0 3232 1400 1032 S 0.0 0.0 0:00.00 goroutines1
3950 USER 20 0 3232 1400 1032 S 0.0 0.0 0:00.00 goroutines1
3951 USER 20 0 3232 1400 1032 S 0.0 0.0 0:00.00 goroutines1
3952 USER 20 0 3232 1400 1032 S 0.0 0.0 0:00.00 goroutines1
3953 USER 20 0 3232 1400 1032 S 0.0 0.0 0:00.00 goroutines1
Where PID 3949 is the main thread.
Where can I find the spec/information about the other 4 threads being run by Go runtime?
