```rust extern crate nix; extern crate procreader; use nix::unistd::Pid; use procreader::ProcReader; use std::process::Command; use std::io::Read; use std::time::Duration; use std::thread;
fn main() { // Create a process for reading stdout let mut child = Command::new("sh").arg("-c").arg("sleep 1; echo aaa").spawn().unwrap();
// Create ProcReader from pid
let pid = Pid::from_raw(child.id() as i32);
let mut reader = ProcReader::from_stdout(pid);
// Wait the end of process
thread::sleep(Duration::from_secs(2));
// Read from ProcReader
let mut line = String::new();
let _ = reader.read_to_string(&mut line);
