Functions ¶

func GetSize ¶

func GetSize(fd int) (int, int, error)

GetSize returns the dimensions of the given terminal.

func IsTerminal ¶

func IsTerminal(fd int) bool

IsTerminal returns true if the given file descriptor is a terminal.

func OpenPty ¶

func OpenPty(uid, gid int64) (*os.File, *os.File, error)

OpenPty creates a new PTS pair, configures them and returns them.

func OpenPtyInDevpts(devpts_fd int, uid, gid int64) (*os.File, *os.File, error)

OpenPtyInDevpts creates a new PTS pair, configures them and returns them.

func Restore ¶

func Restore(fd int, state *State) error

Restore restores the terminal connected to the given file descriptor to a previous state.

func SetSize ¶

func SetSize(fd int, width int, height int) (err error)

SetSize sets the dimensions of the terminal associated with fd.

Types ¶

type State ¶

type State struct {
	Termios unix.Termios
}

State contains the state of a terminal.

func GetState ¶

func GetState(fd int) (*State, error)

GetState returns the current state of a terminal which may be useful to restore the terminal after a signal.

func MakeRaw ¶

func MakeRaw(fd int) (*State, error)

MakeRaw put the terminal connected to the given file descriptor into raw mode and returns the previous state of the terminal so that it can be restored.
