package runtime
Golang runtime.Stack() function usage example.
package main
import (
"fmt"
"runtime"
)
func echo(s string) {
for i := 0; i < 5; i++ {
runtime.Gosched() // see http://golang.org/pkg/runtime/#Gosched
fmt.Println(s)
}
}
func main() {
// maximize CPU usage for multi threading
runtime.GOMAXPROCS(runtime.NumCPU())
buffer := make([]byte, 4096)
buffer = buffer[:runtime.Stack(buffer, true)]
go echo("bye") // schedule this execution on a new thread [second]
go echo("world") // [third]
echo("good") // current [first thread]
fmt.Println("# go routines : ", runtime.NumGoroutine())
fmt.Println("Stack trace bytes : ")
fmt.Println(buffer)
}
