Constants ¶

SIGWINCH is the Window size change signal.

func DumpStack ¶

func GetWinsize ¶

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

func IsATTY ¶

IsATTY returns true if the given file is a terminal.

func NotifySignals ¶

func Select ¶

func Tcsetpgrp ¶

func WaitForRead ¶

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.

type FdSet ¶

func NewFdSet ¶

func (*FdSet) Clear ¶

func (*FdSet) IsSet ¶

func (*FdSet) Set ¶

func (*FdSet) Zero ¶

type Termios ¶

Termios represents terminal attributes.

func TermiosForFd ¶

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

func (*Termios) ApplyToFd ¶

ApplyToFd applies term to the given file descriptor.

func (*Termios) Copy ¶

Copy returns a copy of term.

func (*Termios) SetEcho ¶

SetEcho sets the echo flag.

func (*Termios) SetICRNL ¶

SetICRNL sets the CRNL iflag bit

func (*Termios) SetICanon ¶

SetICanon sets the canonical flag.

func (*Termios) SetIExten ¶

SetIExten sets the iexten flag.

func (*Termios) SetVMin ¶

SetVMin sets the minimal number of characters for noncanonical read.

func (*Termios) SetVTime ¶

SetVTime sets the timeout in deciseconds for noncanonical read.
