});

## Event: 'message'

* `message` {Object} a parsed JSON object or primitive value

* `sendHandle` {Handle object} a [net.Socket][] or [net.Server][] object, or

undefined.

Messages sent by [ChildProcess.send()][] are obtained using the `'message'`

event on the child's process object.

## Event: 'beforeExit'

This event is emitted when Node.js empties its event loop and has nothing else to

}, 1000);

## process.send(message[, sendHandle][, callback])

* `message` {Object}

* `sendHandle` {Handle object}

When Node.js is spawned with an IPC channel attached, it can send messages to its

parent process using `process.send()`. Each will be received as a

['message'](child_process.html#child_process_event_message)

event on the parent's `ChildProcess` object.

If io.js was not spawned with an IPC channel, `process.send()` will be undefined.

## process.disconnect()

Close the IPC channel to the parent process, allowing this child to exit

gracefully once there are no other connections keeping it alive.

Identical to the parent process's

[ChildProcess.disconnect()](child_process.html#child_process_child_disconnect).

If io.js was not spawned with an IPC channel, `process.disconnect()` will be

undefined.

### process.connected

* {Boolean} Set to false after `process.disconnect()` is called

If `process.connected` is false, it is no longer possible to send messages.

## process.mainModule

Alternate way to retrieve

As with `require.main`, it will be `undefined` if there was no entry script.
