Snap for 8736029 from 5e7c71c16780bfb9add341b260ee34679019b351 to mainline-go-adbd-release Change-Id: I6a722a5b344f0eabae6bb53b2a64211eabcfbf92
A library for passing arbitrary file descriptors when spawning child processes.
use command_fds::{CommandFdExt, FdMapping}; use std::fs::File; use std::os::unix::io::AsRawFd; use std::process::Command; // Open a file. let file = File::open("Cargo.toml").unwrap(); // Prepare to run `ls -l /proc/self/fd` with some FDs mapped. let mut command = Command::new("ls"); command.arg("-l").arg("/proc/self/fd"); command .fd_mappings(vec![ // Map `file` as FD 3 in the child process. FdMapping { parent_fd: file.as_raw_fd(), child_fd: 3, }, // Map this process's stdin as FD 5 in the child process. FdMapping { parent_fd: 0, child_fd: 5, }, ]) .unwrap(); // Spawn the child process. let mut child = command.spawn().unwrap(); child.wait().unwrap();
