PidFd

Struct PidFd 

Source
pub struct PidFd(/* private fields */);
Expand description

File descriptor RAII qui référence un processus par pidfd.

Ferme automatiquement le FD sous-jacent à la destruction. Reste valide même après la mort du processus référencé (le FD ne se transfère pas à un éventuel nouveau processus qui recyclerait le PID).

Implementations§

Source§

impl PidFd

Source

pub const fn from_owned_fd(fd: OwnedFd) -> Self

Construit un PidFd à partir d’un OwnedFd déjà ouvert sur un processus par le kernel (typiquement via pidfd_open ou clone3 avec CLONE_PIDFD).

Source

pub fn as_fd(&self) -> BorrowedFd<'_>

Retourne une vue empruntée du FD sous-jacent.

Source

pub fn into_fd(self) -> OwnedFd

Consomme le PidFd et restitue le OwnedFd sous-jacent.
