pidfd_getfd

This crate provides a direct binding to the pidfd_getfd syscall, as well as a slightly more convenient wrapper, get_file_from_pidfd. This also contains an extension trait for the pidfd crate which provides access to pidfd_getfd via PidFdExt::get_fd().

Please note that this crate has not been thoroughly tested. Viewer discretion is advised.

Example

use pidfd_getfd::{get_file_from_pidfd, GetFdFlags};
use std::io::Read;

let pidfd: RawFd = /* ... */;
let target_fd: RawFd = /* ... */;
let file = get_file_from_pidfd(pidfd, target_fd, GetFdFlags::empty());
let mut buf = Vec::new();
file.read_to_end(&mut buf)?;
println!("{:#?}", buf);
