been closed. This is distinct from the [`'exit'`][] event, since multiple
processes might share the same stdio streams.

```js
const { spawn } = require('child_process');
const ls = spawn('ls', ['-lh', '/usr']);

ls.stdout.on('data', (data) => {
console.log(`stdout: ${data}`);
});

ls.on('close', (code) => {
console.log(`child process close all stdio with code ${code}`);
});

ls.on('exit', (code) => {
console.log(`child process exited with code ${code}`);
});
```

### Event: 'disconnect'
