Functions ¶

func DumpStack ¶

func DumpStack() string

func GetWinsize ¶

func GetWinsize(file *os.File) (row, col int)

GetWinsize queries the size of the terminal referenced by the given file.

func IsATTY ¶

func IsATTY(file *os.File) bool

IsATTY returns true if the given file is a terminal.

func NotifySignals ¶ added in v0.15.0

func NotifySignals() chan os.Signal

func Select ¶

func Select(nfd int, r *FdSet, w *FdSet, e *FdSet, timeout time.Duration) error

func Tcsetpgrp ¶

func Tcsetpgrp(fd int, pid int) error

func WaitForRead ¶

func WaitForRead(timeout time.Duration, files ...*os.File) (ready []bool, err error)

WaitForRead blocks until any of the given files is ready to be read or timeout. A negative timeout means no timeout. It returns a boolean array indicating which files are ready to be read and any possible error.

func (fs *FdSet) IsSet(fd int) bool

func (*FdSet) Set ¶

func (fs *FdSet) Set(fds ...int)

func (*FdSet) Zero ¶

func (fs *FdSet) Zero()

type Termios ¶

type Termios unix.Termios

Termios represents terminal attributes.

func TermiosForFd ¶ added in v0.15.0

func TermiosForFd(fd int) (*Termios, error)

TermiosForFd returns a pointer to a Termios structure if the file descriptor is open on a terminal device.
