  [out, optional] void    *pData
);

Parameters

[in] guid

Type: REFGUID

Guid associated with the data.

[in, out] pDataSize

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 buffer that GetPrivateData fills with data from the device 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 codes described in the topic Direct3D 11 Return Codes.
