Update TEST_MAPPING am: bad4ff2b87 am: 9c86e6a14d am: 7b65e9544b am: 25cb0b2625 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/command-fds/+/2005941 Change-Id: I31b53a68d7a8d1bb40261d7964dc0d87705eafca
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();
