  • Article

Gets application-defined data from a device object.

Syntax

HRESULT GetPrivateData(
  [in]            REFGUID guid,
  [in, out]       UINT    *pDataSize,
  [out, optional] void    *pData
);

Parameters

[in] guid

Type: REFGUID

The GUID that is associated with the data.

[in, out] pDataSize

Type: UINT*

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

[out, optional] pData

Type: void*

A pointer to a memory block that receives the data from the device object if pDataSize 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.

Remarks

If the data returned is a pointer to an 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.
