Just fine. The problem is you haven't created any file to write to in the
first place, which checking the error could have told you.

[go-nuts] [ERROR] invalid argument when executing bufio.NewWriter.Flush()

[Harry]

Hi guys,

How can I handle to write something out using bufio.NewWriter?

My code is like below,

var writer *bufio.Writer
var err error
file, _ := os.OpenFile(*fileName, os.O_WRONLY | os.O_APPEND, 0644)
defer file.Close()

writer = bufio.NewWriter(file)

writer.WriteString(strings.Join("something\n")

err = writer.Flush()
if err != nil {
//invalid argument
log.Fatal(err)
}


What is wrong?


Thanks guys!!
