# GameInputEnumerationKind

> GameInputEnumerationKind

Enumerates types of behavior for enumerating input devices.

## 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](https://docs.xbox.com/reference/input/gameinput/interfaces/igameinput/methods/igameinput_registerdevicecallback.md) 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](https://docs.xbox.com/build/core-features/common/input/advanced/input-callbacks.md).

## Requirements

**Header:** GameInput.h

**Supported platforms:** Windows, XBOX One family consoles and XBOX Series consoles
