# D3D12_GPU_DESCRIPTOR_HANDLE

> Describes a GPU descriptor handle.

Describes a GPU descriptor handle.

## Syntax

```cpp theme={null}
typedef struct D3D12_GPU_DESCRIPTOR_HANDLE
{
    UINT64 ptr;
} D3D12_GPU_DESCRIPTOR_HANDLE
```

### Members

*ptr*\
Type: UINT64

The address of the descriptor.

## Remarks

This structure is returned by [ID3D12DescriptorHeap::GetGPUDescriptorHandleForHeapStart](/reference/graphics/d3d12/interfaces/id3d12descriptorheap/methods/id3d12descriptorheap_getgpudescriptorhandleforheapstart_public).

This structure is passed into the following methods:

<ul>
  <li>
    [ID3D12GraphicsCommandList::ClearUnorderedAccessViewFloat](/reference/graphics/d3d12/interfaces/id3d12graphicscommandlist/methods/id3d12graphicscommandlist_clearunorderedaccessviewfloat_public)
  </li>

  <li>
    [ID3D12GraphicsCommandList::ClearUnorderedAccessViewUint](/reference/graphics/d3d12/interfaces/id3d12graphicscommandlist/methods/id3d12graphicscommandlist_clearunorderedaccessviewuint_public)
  </li>

  <li>
    [ID3D12GraphicsCommandList:SetComputeRootDescriptorTable](/reference/graphics/d3d12/interfaces/id3d12graphicscommandlist/methods/id3d12graphicscommandlist_setcomputerootdescriptortable_public)
  </li>

  <li>
    [ID3D12GraphicsCommandList::SetGraphicsRootDescriptorTable](/reference/graphics/d3d12/interfaces/id3d12graphicscommandlist/methods/id3d12graphicscommandlist_setgraphicsrootdescriptortable_public)
  </li>
</ul>

To get the handle increment size use [ID3D12Device.GetDescriptorHandleIncrementSize](/reference/graphics/d3d12/interfaces/id3d12device/methods/id3d12device_getdescriptorhandleincrementsize_public)

## 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
