goloang readFile into Buffer.md

How to read file into a buffer i.e. using chunks

package main

import (
	"bufio"
	"flag"
	"fmt"
	"io"
	"log"
	"os"
)

func main() {
	fPath := flag.String("fPath", "src/tg_io/data.txt", "name of the file location to read")
	flag.Parse()

	f, err := os.Open(*fPath)
	defer func() {
		if err := f.Close(); err != nil {
			log.Fatal(err)
		}
	}()
	if err != nil {
		log.Fatal(err)
	}

	r := bufio.NewReader(f)
	b := make([]byte, 3)

	for {
		n, err := r.Read(b)
		if err != nil {
			if err != io.EOF {
				log.Fatal(err)
			} else {
				fmt.Println("EOF recieved")
			}
			break
		}
		fmt.Printf("Read #bytes = %v. Data = %q \n", n, string(b[:n]))

	}

	// fmt.Println(string(*fPath))
}
