Struct std::os::linux::process::PidFd
pub struct PidFd { /* fields omitted */ }
This type represents a file descriptor that refers to a process.
A PidFd can be obtained by setting the corresponding option on Command with create_pidfd. Subsequently, the created pidfd can be retrieved from the Child by calling pidfd or take_pidfd.
Example:
#![feature(linux_pidfd)]
use std::os::linux::process::{CommandExt, ChildExt};
use std::process::Command;
let mut child = Command::new("echo")
.create_pidfd(true)
.spawn()
.expect("Failed to spawn child");
let pidfd = child
.take_pidfd()
.expect("Failed to retrieve pidfd");
// The file descriptor will be closed when `pidfd` is dropped.Refer to the man page of pidfd_open(2) for further details.
