本文介紹如何打印調(diào)用堆棧進(jìn)行go代碼的調(diào)試。
打印堆棧使用的runtime package中的Stack()函數(shù)

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. |
