## Signature

```c
BOOL IS_UIAPP_RUNNING_BY_HASH(Hash appNameHash);
```

## Parameters

- `appNameHash` (`Hash`)

## Returns

`BOOL`

## Description

*Source: VORPCORE RDR3natives*

Checks to see if the specified UI app is currently running by its hash.

## Usage

### Lua

```lua
local retval = IsUiappRunningByHash(appNameHash)

-- always available, by hash
local retval = Citizen.InvokeNative(0x4E511D093A86AD49, appNameHash, Citizen.ReturnResultAnyway())
```

### JavaScript

```js
const retval = IsUiappRunningByHash(appNameHash);

// by hash
const retval = Citizen.invokeNative('0x4E511D093A86AD49', appNameHash, Citizen.returnResultAnyway());
```

### C#

```csharp
bool retval = Function.Call<bool>((Hash)0x4E511D093A86AD49, appNameHash);
```

- Hash parameters: the named function also accepts a string and hashes it for you; `Citizen.InvokeNative` needs the number — pass `joaat("name")` or a backtick literal like `` `name` ``.

## Examples

*Source: VORPCORE RDR3natives*

```lua
if IsUiappActiveByHash(`PAUSE_MENU`) then
   CloseUiappByHashImmediate(`PAUSE_MENU`)
end
```
