TerminalState

kaish_kernel::terminal

Struct TerminalState 

Source 
pub struct TerminalState { /* private fields */ }
Expand description

Terminal state for interactive job control.

Created once at REPL startup. Manages signal disposition and terminal foreground process group.

Implementations§

Source§

impl TerminalState

Source

pub fn init() -> Result<Self>

Initialize terminal state for interactive job control.

  • Puts the shell in its own process group
  • Ignores SIGTSTP, SIGTTOU, SIGTTIN (so the shell isn’t stopped)
  • Takes the terminal foreground
Source

pub fn give_terminal_to(&self, pgid: Pid) -> Result<()>

Give the terminal foreground to a process group.

Source

pub fn reclaim_terminal(&self) -> Result<()>

Reclaim the terminal foreground for the shell.

Source

pub fn wait_for_foreground(&self, pid: Pid) -> WaitResult

Wait for a foreground process, handling stop signals (WUNTRACED).

This blocks the current thread. Call from block_in_place.
