buf := bytes.NewBufferString("hello world") buf.WriteTo(file)//或者使用写入,fmt.Fprintf(file,buf.String())} 四、读出缓冲器 1、Read方法,给Read方法一个容器,读完后p就满了,缓冲器相应的减少。 // func (b *Buffer) Read(p []byte)(n int,err error)funcmain(){ ...
Notice treating EOF.Readtries to fillbufon each call, and returnsio.EOFas error if it reaches end of file in doing so. In this casebufwill still hold data. Consequent calls toReadreturns zero as the number of bytes read and sameio.EOFas error. Any other error will lead to a panic. ...
The end of the archive is indicated by two records consisting entirely of zero bytes. The Go implementation of adding these two zero filled records happens here . To get around the tar file format trailer (basically 1024 bytes of nothing) you could replace the lines: f, err = os.OpenFile...

I am making a go program where I need to write a gob to a file. I used the .String() method to convert the gob to a string. var network bytes.Buffer encoder := gob.NewEncoder(&network) _ = encoder.Encode(valueToEncode) gobString := network.String() then I will write the gob...
