> 可輕鬆初始化 D3D12_CPU_DESCRIPTOR_HANDLE 結構的輔助結構。

可輕鬆初始化 [D3D12\_CPU\_DESCRIPTOR\_HANDLE](https://learn.microsoft.com/en-us/windows/win32/api/d3d12/ns-d3d12-d3d12_cpu_descriptor_handle) 結構的輔助結構。

## 語法

```cpp theme={null}
struct CD3DX12_CPU_DESCRIPTOR_HANDLE : public D3D12_CPU_DESCRIPTOR_HANDLE {  
}  
```

## 備註

CD3DX12\_CPU\_DESCRIPTOR\_HANDLE 的定義如下：

```cpp theme={null}
struct CD3DX12_CPU_DESCRIPTOR_HANDLE : public D3D12_CPU_DESCRIPTOR_HANDLE
{
    CD3DX12_CPU_DESCRIPTOR_HANDLE();
    CD3DX12_CPU_DESCRIPTOR_HANDLE(const D3D12_CPU_DESCRIPTOR_HANDLE &o);
    CD3DX12_CPU_DESCRIPTOR_HANDLE(CD3DX12_DEFAULT);
    CD3DX12_CPU_DESCRIPTOR_HANDLE(_In_ const D3D12_CPU_DESCRIPTOR_HANDLE &other, INT offsetScaledByIncrementSize);
    CD3DX12_CPU_DESCRIPTOR_HANDLE(_In_ const D3D12_CPU_DESCRIPTOR_HANDLE &other, INT offsetInDescriptors, UINT descriptorIncrementSize);
    CD3DX12_CPU_DESCRIPTOR_HANDLE& Offset(INT offsetInDescriptors, UINT descriptorIncrementSize);
    CD3DX12_CPU_DESCRIPTOR_HANDLE& Offset(INT offsetScaledByIncrementSize);
    bool operator==(_In_ const D3D12_CPU_DESCRIPTOR_HANDLE& other) const;
    bool operator!=(_In_ const D3D12_CPU_DESCRIPTOR_HANDLE& other) const;
    CD3DX12_CPU_DESCRIPTOR_HANDLE &operator=(const D3D12_CPU_DESCRIPTOR_HANDLE &other);
    void InitOffsetted(_In_ const D3D12_CPU_DESCRIPTOR_HANDLE &base, INT offsetScaledByIncrementSize);
    void InitOffsetted(_In_ const D3D12_CPU_DESCRIPTOR_HANDLE &base, INT offsetInDescriptors, UINT descriptorIncrementSize);
    static void InitOffsetted(_Out_ D3D12_CPU_DESCRIPTOR_HANDLE &handle, _In_ const D3D12_CPU_DESCRIPTOR_HANDLE &base, INT offsetScaledByIncrementSize);
    static void InitOffsetted(_Out_ D3D12_CPU_DESCRIPTOR_HANDLE &handle, _In_ const D3D12_CPU_DESCRIPTOR_HANDLE &base, INT offsetInDescriptors, UINT descriptorIncrementSize);
    void* GetWritePointerX() const;
    const void* GetCachedReadPointerX() const;
};
