go 代码的调试---打印调用堆栈的实例_Golang_

 func Stack(buf []byte, all bool) int Stack formats a stack trace of the calling goroutine into buf and returns the number of bytes written to buf. If all is true, Stack formats stack traces of all other goroutines into buf after the trace for the current goroutine.

 package main import ( "runtime" "time" "fmt" ) func main() { go power1() for { time.Sleep(time.Duration(1)*time.Minute) } } func power1(){ var buf [1024]byte fmt.Println("power1.....") n := runtime.Stack(buf[:], true) fmt.Println(string(buf[:]), n) }
