# GetAdapterLuid

> Gets a locally unique identifier for the current device (adapter).

Gets a locally unique identifier for the current device (adapter).

## Syntax

```cpp theme={null}
LUID GetAdapterLuid(
)
```

### Parameters

### Return value

Type: LUID

The locally unique identifier for the adapter.

## Remarks

This method returns a unique identifier for the adapter that is specific to the adapter hardware.
Applications can use this identifier to define robust mappings across various APIs (Direct3D 12, DXGI).

A locally unique identifier (LUID) is a 64-bit value that is guaranteed to be unique only on the system on which it was generated.
The uniqueness of a locally unique identifier (LUID) is guaranteed only until the system is restarted.

## Requirements

**Header:** d3d12\_xs.h or d3d12\_x.h\
**Library:** d3d12\_xs.lib or d3d12\_x.lib\
**Supported Platforms**: XBOX Series consoles and XBOX One family
