# GameInputEnumerationKind

Enumerates types of behavior for enumerating input devices.

<a id="syntaxSection" />

## Syntax

```cpp theme={null}
enum GameInputEnumerationKind
{
    GameInputNoEnumeration       = 0,
    GameInputAsyncEnumeration    = 1,
    GameInputBlockingEnumeration = 2
};
```

## Constants

| Constant                     | Description                              |
| ---------------------------- | ---------------------------------------- |
| GameInputNoEnumeration       | Disables enumeration of input devices.   |
| GameInputAsyncEnumeration    | Enumerates input devices asynchronously. |
| GameInputBlockingEnumeration | Enumerates input devices synchronously.  |

## Remarks

This enumeration is used by the [IGameInput::RegisterDeviceCallback](/reference/input/gameinput/interfaces/igameinput/methods/igameinput_registerdevicecallback) method. Both `GameInputAsyncEnumeration` and `GameInputBlockingEnumeration` cause an initial round of callbacks to be generated. `GameInputBlockingEnumeration` causes `RegisterDeviceCallback` to block until all initial callbacks are called.

For more information, see [GameInput callbacks](/build/core-features/common/input/advanced/input-callbacks).
