CloneResult

Enum CloneResult 

Source
pub enum CloneResult {
    Parent {
        child_pid: Pid,
        child_pidfd: Option<PidFd>,
    },
    Child,
}
Expand description

Résultat de clone3.

Distingue sans ambiguïté le côté parent (avec le PID enfant et, optionnellement, un pidfd) du côté enfant (qui n’a rien d’autre à connaître que sa propre identité, accessible via getpid/gettid).

Variants§

§

Parent

Retour côté parent.

Fields

§child_pid: Pid

PID du nouvel enfant.

§child_pidfd: Option<PidFd>

PidFd si CloneFlags::PIDFD était positionné, None sinon.

§

Child

Retour côté enfant.

L’enfant doit typiquement exécuter ses traitements puis terminer (exit_group, ou — dans les tests Air — std::process::exit qui flush les compteurs LLVM de couverture). Voir le pattern recommandé dans la spec.
