Static defaultMaxListeners

defaultMaxListeners: number

Static Readonly errorMonitor

errorMonitor: unique symbol

This symbol shall be used to install a listener for only monitoring 'error' events. Listeners installed using this symbol are called before the regular 'error' listeners are called.

Installing a listener using this symbol does not change the behavior once an 'error' event is emitted, therefore the process will still crash if no regular 'error' listener is installed.
