## Description

A non-existing [Config](../topics/Config.md).

> [!IMPORTANT]

>
> ```sqf
> configNull == configNull;                            // returns true
> isNull configNull;                                    // returns true
> configNull isEqualTo configNull;                    // returns true
> configNull == configFile >> "ANonExistentEntry";    // returns true
> ```
