# GetPrivateData

> Gets application-defined data from a device object.

Gets application-defined data from a device object.

## Syntax

```cpp theme={null}
HRESULT GetPrivateData(
    const GUID & guid,
    UINT  pDataSize,
    void  pData
)
```

### Parameters

*guid \[in]*\
Type: const GUID &

The **GUID** that is associated with the data.

*pDataSize \[in, out]*\
Type: UINT \*

A pointer to a variable that on input contains the size, in bytes, of the buffer that <i>pData</i> points to, and on output contains the size, in bytes, of the amount of data that **GetPrivateData** retrieved.

*pData \[out, optional]*\
Type: void \*

A pointer to a memory block that receives the data from the device object if <i>pDataSize</i> points to a value that specifies a buffer large enough to hold the data.

### Return value

Type: HRESULT

This method returns one of the [Direct3D 12 Return Codes](https://learn.microsoft.com/en-us/windows/desktop/direct3d12/d3d12-graphics-reference-returnvalues).

## Remarks

If the data returned is a pointer to an [IUnknown](https://learn.microsoft.com/en-us/windows/desktop/api/unknwn/nn-unknwn-iunknown), or one of its derivative classes, which was previously set by SetPrivateDataInterface, that interface will have its reference count incremented before the private data is returned.

## 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
