## Signature

```c
BOOL NETWORK_DOES_TUNABLE_EXIST(Hash tunableContext, Hash tunableName);
```

## Parameters

- `tunableContext` (`Hash`)
- `tunableName` (`Hash`)

## Returns

`BOOL`

## Usage

### Lua

```lua
local retval = NetworkDoesTunableExist(tunableContext, tunableName)

-- always available, by hash
local retval = Citizen.InvokeNative(0x85E5F8B9B898B20A, tunableContext, tunableName, Citizen.ReturnResultAnyway())
```

### JavaScript

```js
const retval = NetworkDoesTunableExist(tunableContext, tunableName);

// by hash
const retval = Citizen.invokeNative('0x85E5F8B9B898B20A', tunableContext, tunableName, Citizen.returnResultAnyway());
```

### C#

```csharp
bool retval = Function.Call<bool>((Hash)0x85E5F8B9B898B20A, tunableContext, tunableName);
```

- 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` ``.
