Hi,
The following example shows how to write a byte slice to a buffer. But
what if I want only write a length shorter (say 2 instead of 5) than
the size of the slice. Is there a function that allows users to
specify the length to write? Thanks.
$ cat main.go
#!/usr/bin/env gorun
// vim: set noexpandtab tabstop=2:
package main
import (
"os"
"bufio"
"fmt"
)
func main() {
f := bufio.NewWriter(os.Stdout)
d := []byte{'s', 'o', 'm', 'e', '\n'}
n, err := f.Write(d)
f.Flush()
fmt.Printf("wrote %d bytes, error %q\n", n, err)
}
