Struct ZombiePtracees 

pub struct ZombiePtracees { /* private fields */ }

A list of zombie processes that were traced by a given tracer, but which have not yet notified that tracer of their exit. Once the tracer is notified, the original parent will be notified.

Implementations

impl ZombiePtracees

pub fn new() -> Self

pub fn add(&mut self, pids: &mut PidTable, tid: tid_t, zombie: ZombieProcess)

Adds a zombie tracee to the list, but does not provide a parent task to notify when the tracer is done.

pub fn remove(&mut self, pids: &mut PidTable, tid: tid_t)

Delete any zombie ptracees for the given tid.

pub fn is_empty(&self) -> bool

pub fn set_parent_of( &mut self, tracee: tid_t, new_zombie: Option<OwnedRef<ZombieProcess>>, new_parent: &ThreadGroup, )

Provide a parent task and a zombie to notify when the tracer has been notified.

pub fn reparent(old_parent: &ThreadGroup, new_parent: &ThreadGroup)

When a parent dies without having been notified, replace it with a given new parent.

pub fn release(&mut self, pids: &mut PidTable)

Empty the table and notify all of the remaining parents. Used if the tracer terminates or detaches without acknowledging all pending tracees.

pub fn has_zombie_matching(&self, selector: &ProcessSelector) -> bool

Returns true iff there is a zombie waiting to be delivered to the tracers matching the given selector.

pub fn has_tracee(&self, tid: tid_t) -> bool

Returns true iff the given tid is a traced thread that needs to deliver a zombie to the tracer.

pub fn get_waitable_entry( &mut self, selector: &ProcessSelector, options: &WaitingOptions, ) -> Option<(ZombieProcess, Option<(Weak<ThreadGroup>, OwnedRef<ZombieProcess>)>)>

Returns a zombie matching the given selector and options, and (optionally) a thread group to notify after the caller has consumed that zombie.

impl Default for ZombiePtracees

fn default() -> ZombiePtracees

Returns the “default value” for a type.
