ReadAll in Go

Posted by GoDoc

ReadAll reads from r until an error or EOF and returns the data it read. A successful call returns err == nil, not err == EOF. Because ReadAll is defined to read from src until EOF, it does not treat an EOF from Read as an error to be reported.

Go

package main

import (
	"fmt"
	"io/ioutil"
	"log"
	"strings"
)

func main() {
	r := strings.NewReader("Go is a general-purpose language designed with systems programming in mind.")

	b, err := ioutil.ReadAll(r)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Printf("%s", b)
}
