如何在golang中关闭bufio.Reader/Writer？

Question

我怎么能关闭bufio.Reader或bufio.Writer在golang？

func init(){
    file,_ := os.Create("result.txt")
    writer = bufio.NewWriter(file)
}

我应该关闭Writer吗？或者只是使用file.Close()会Writer关闭？

Answer 1

据我所知,你无法关闭bufio.Writer.

你做的是Flush()对bufio.Writer,然后Close()在os.Writer:

writer.Flush()
file.Close()
