csv - 同时创建和写入两个CSV golang

Question

我正在尝试创建两个CSV文件并同时写入两者。这段代码不能那样工作，而只是为了说明我想做的事情。由于(* csv.Writer)是一个指针，所以我不知道如何将其与另一个文件区分开。有可能这样做吗？

package test

import (
    "encoding/csv"
    "os"
    "sync"
    "time"
)

var csvSuccess *os.File
var csvError *os.File
var csvErr error
var csvWriterSuccess *csv.Writer
var csvWriterError *csv.Writer
var mutex *sync.Mutex

func init() {
    csvSuccess, csvErr = os.Create("sucess-result.csv")
    csvError, csvErr = os.Create("error-result.csv")
    if csvErr != nil {
        panic("Error open file")
    }
    csvWriterSuccess = csv.NewWriter(csvSuccess)
    csvWriterError = csv.NewWriter(csvSuccess)
    mutex = &sync.Mutex{}
}

func WriteRecordSuccess(record []string) {
    mutex.Lock()
    if err := csvWriterSuccess.Write(record); err != nil {
        if err != nil {
            panic("Error writing success record")
        }
        csvWriterSuccess.Flush()
    }
    mutex.Unlock()
}

func WriteRecordError(record []string) {
    mutex.Lock()
    if err := csvWriterError.Write(record); err != nil {
        if err != nil {
            panic("Error writing error record")
        }
        csvWriterError.Flush()
    }
    mutex.Unlock()
}

func ClosecsvFile() {
    csvWriterSuccess.Flush()
    csvWriterError.Flush()
    csvSuccess.Sync()
    csvError.Sync()
    csvSuccess.Close()
    csvError.Close()
}

在init函数中，两位作者都写入成功文件。

csvWriterSuccess = csv.NewWriter(csvSuccess)
csvWriterError = csv.NewWriter(csvSuccess)

分别写入成功和错误文件。

csvWriterSuccess = csv.NewWriter(csvSuccess)
csvWriterError = csv.NewWriter(csvError)
