Implementations

impl PidEntry

pub fn get_task(&self) -> Result<Arc<Task>, Errno>

pub fn get_process_task(&self) -> Option<Arc<Task>>

Returns a representative Task for this process, including when the thread-group leader has exited or the process is an unreaped zombie.

pub fn get_process(&self) -> Option<ProcessEntryRef>

pub fn get_thread_group(&self) -> Result<Arc<ThreadGroup>, Errno>

pub fn is_process_group(&self, scope: &RcuReadScope) -> bool

Returns whether any member thread groups belong to this process group (PGID).

pub fn is_session(&self, scope: &RcuReadScope) -> bool

Returns whether any member thread groups belong to this session (SID).

pub fn pgid_thread_groups<'a>( &'a self, scope: &'a RcuReadScope, ) -> impl Iterator<Item = Arc<ThreadGroup>> + 'a

Returns an iterator over the member thread groups in this process group (PGID).

pub fn sid_thread_groups<'a>( &'a self, scope: &'a RcuReadScope, ) -> impl Iterator<Item = Arc<ThreadGroup>> + 'a

Returns an iterator over the member thread groups in this session (SID).

pub fn is_process_group_in_session( &self, session: &PidEntry, scope: &RcuReadScope, ) -> bool

Returns whether this process group (PGID) is non-empty and belongs to session (SID).

pub fn clear_controlling_terminal( &self, matching: Option<(&Terminal, Option<TerminalSide>)>, )

Clears the controlling terminal on all member thread groups in this session (SID).

If matching is Some((terminal, maybe_side)), only clears controlling_terminal if it refers to terminal (and matches side if specified).

pub fn will_become_orphaned_pgrp( &self, scope: &RcuReadScope, ignored_tg: Option<&ThreadGroup>, ) -> bool

Returns whether the process group represented by this PidEntry is orphaned.

An orphaned process group is one where every member’s parent is either in the same process group or outside the group’s session.

If ignored_tg is supplied, that thread group is ignored during traversal.

pub fn has_stopped_jobs(&self, scope: &RcuReadScope) -> bool

Returns whether any member in this process group is stopped by job control.

pub fn send_signals_to_pgid(&self, signals: &[Signal])

Dispatches signals to all member thread groups in this process group.

Signals are delivered in order: each signal in signals is delivered to all group members before the subsequent signal is dispatched.
