# Struct std::os::linux::process::PidFd
[−][src]

    pub struct PidFd { /* fields omitted */ }

🔬 This is a nightly-only experimental API. (`linux_pidfd` #82971)
This is supported on Linux only.
Expand description

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.

Run

Refer to the man page of `pidfd_open(2)` for further details.
