```

## Parameters

`BOOL`

## Usage

### Lua

```lua
local retval = IsBackgroundScript(threadId)

-- always available, by hash
local retval = Citizen.InvokeNative(0x20B7F69B40C6B755, threadId, Citizen.ReturnResultAnyway())
```

### JavaScript

```js
const retval = IsBackgroundScript(threadId);

// by hash
const retval = Citizen.invokeNative('0x20B7F69B40C6B755', threadId, Citizen.returnResultAnyway());
```

### C#

```csharp
bool retval = Function.Call<bool>((Hash)0x20B7F69B40C6B755, threadId);
```

- The name is a community guess and may change. If the named call is missing in your client build, use `InvokeNative` with the hash — it always works.
