# D3D12_GPU_DESCRIPTOR_HANDLE

> 描述 GPU 描述元控制代碼。

描述 GPU 描述元控制代碼。

## 語法

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

### 成員

*ptr*\
類型：UINT64

描述元的位址。

## 備註

此結構由 [ID3D12DescriptorHeap::GetGPUDescriptorHandleForHeapStart](/zh-TW/reference/graphics/d3d12/interfaces/id3d12descriptorheap/methods/id3d12descriptorheap_getgpudescriptorhandleforheapstart_public) 傳回。
