# isClient

## Category
Multiplayer

## Arity
**Nular** — `isClient`.

```
isClient
```

## Description
Returns the **inverse** of `isServer`. Returns `true` if the current process is a client, `false` if it is the server. In the SQ# host, this is always `false` (the host is the server).

Registered by `DeclareMultiplayerCommands()`. **NOT called automatically** — host must invoke explicitly.

## How It Works
Returns `!isServer`. Purely for Arma SQF compatibility.

## Usage

```sqf
if (isClient) then {
    // Client-only logic (never runs in SQ# host by default)
};
```

## Thread Safety
ReadOnly — pure query.
