You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: password_supported.go
    path of file: ./repos/podman/vendor/github.com/containers/common/pkg/password
    
    the code of the file until where you have to start completion: //go:build linux || darwin || freebsd

package password

import (
	"errors"
	"os"
	"os/signal"
	"syscall"

	terminal "golang.org/x/term"
)

var ErrInterrupt = errors.New("interrupted")

// Read reads a password from the terminal without echo.
func Read(fd int) ([]byte, error) {
	// Store and restore the terminal status on interruptions to
	// avoid that the terminal remains in the password state
	// This is necessary as for https://github.com/golang/go/issues/31180

	oldState, err := terminal.GetState(fd)
	if err != nil {
		return make([]byte, 0), err
	}

	type Buffer struct {
		Buffer []byte
		Error  error
	}
	errorChannel := make(chan Buffer, 1)

	// SIGINT and SIGTERM restore the terminal, otherwise the no-echo mode would remain intact
	interruptChannel := make(chan os.Signal, 1)
	signal.Notify(interruptChannel, syscall.SIGINT, syscall.SIGTERM)
	defer func() {
		signal
    
func Read(fd int) ([]byte, error) {
	// Store and restore the terminal status on interruptions to
	// avoid that the terminal remains in the password state
	// This is necessary as for https://github.com/golang/go/issues/31180

	oldState, err := terminal.GetState(fd)
