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: termios.go
    path of file: ./repos/kubernetes/vendor/github.com/moby/term
    
    the code of the file until where you have to start completion: //go:build !windows
// +build !windows

package term

import (
	"golang.org/x/sys/unix"
)

// Termios is the Unix API for terminal I/O.
type Termios
    
func MakeRaw(fd uintptr) (*State, error) {
	termios, err := tcget(fd)
	if err != nil {
		return nil, err
	}

	oldState := State{termios: *termios}

	termios.Iflag &^= (unix.IGNBRK | unix.BRKINT | unix.PARMRK | unix.ISTRIP | unix.INLCR | unix.IGNCR | unix.ICRNL | unix.IXON)
	termios.Oflag &^= unix.OPOST
	termios.Lflag &^= (unix.ECHO | unix.ECHONL | unix.ICANON | unix.ISIG | unix.IEXTEN)
	termios.Cflag &^= (unix.CSIZE | unix.PARENB)
	termios.Cflag |= unix.CS8
	termios.Cc[unix.VMIN] = 1
	termios.Cc[unix.VTIME] = 0

	if err := tcset(fd, termios); err != nil {
		return nil, err
	}
	return &oldState, nil
}
