# D3D12_GPU_DESCRIPTOR_HANDLE

> 描述 GPU 描述符句柄。

描述 GPU 描述符句柄。

## 语法

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

### 成员

*ptr*\
类型:UINT64

描述符的地址。

## 备注

此结构由 [ID3D12DescriptorHeap::GetGPUDescriptorHandleForHeapStart](/reference/graphics/d3d12/interfaces/id3d12descriptorheap/methods/id3d12descriptorheap_getgpudescriptorhandleforheapstart_public) 返回。

此结构被传递到以下方法中:

<ul>
  <li>
