Struct PtyMaster 

pub struct PtyMaster { /* private fields */ }

PTY Master side (controlled by terminal emulator)

Implementations

impl PtyMaster

pub fn new(id: u32) -> Self

Create a new PTY master

pub fn id(&self) -> u32

Get PTY ID

pub fn read(&self, buffer: &mut [u8]) -> Result<usize, KernelError>

Read from slave output (what the slave wrote)

pub fn write(&self, data: &[u8]) -> Result<usize, KernelError>

Write to slave input (what the slave will read)

pub fn set_winsize(&self, winsize: Winsize)

Set window size

pub fn get_winsize(&self) -> Winsize

Get window size

pub fn set_flags(&self, flags: TermiosFlags)

Set terminal flags

pub fn get_flags(&self) -> TermiosFlags

Get terminal flags

pub fn set_controller(&self, pid: ProcessId)

Set the controlling process for this PTY.

The controlling process receives signals (SIGINT, SIGTSTP, SIGWINCH) generated by special terminal characters (^C, ^Z) and window size changes.

pub fn get_controller(&self) -> Option<ProcessId>

Get the controlling process ID, if any.

pub fn set_foreground_pgid(&self, pgid: u64)

Set the foreground process group ID for this terminal.

The foreground process group receives keyboard-generated signals (SIGINT from ^C, SIGTSTP from ^Z). Processes in background groups that attempt to read from or write to this terminal receive SIGTTIN or SIGTTOU respectively.

pub fn get_foreground_pgid(&self) -> u64

Get the foreground process group ID for this terminal.

Returns 0 if no foreground group has been set.
