PFND3DDDI_GETINFO callback function (d3dumddi.h)
The GetInfo function retrieves information about the specified display device.
Syntax
PFND3DDDI_GETINFO Pfnd3dddiGetinfo;
HRESULT Pfnd3dddiGetinfo(
HANDLE hDevice,
UINT unnamedParam2,
VOID *unnamedParam3,
UINT DevInfoSize
)
{...}
Parameters
hDevice
A handle to the display device (graphics context).
unnamedParam2
DevInfoID
An identifier for the type of device information to retrieve.
unnamedParam3
pDevInfoStruct
A pointer to a buffer of the type that DevInfoID specifies that receives information about the device.
DevInfoSize
The size, in bytes, of the buffer that is supplied by pDevInfoStruct.
Return value
GetInfo returns one of the following values:
| Return code | Description |
|---|---|
| S_OK | The device information is successfully retrieved. |
| E_NOTIMPL | The driver does not support the requested type of device information. |
| E_INVALIDARG | Parameters were validated and determined to be incorrect. |
Remarks
The Microsoft DirectX 7 and DirectX 8 runtimes call the GetInfo function to query a user-mode display driver for additional device information.
The Direct3D 8 runtime sets the D3DDDIDEVINFOID_VCACHE flag in the DevInfoID parameter and specifies an empty D3DDDIDEVINFO_VCACHE structure in the pDevInfoStruct parameter to query the user-mode display driver's support for vertex cache.
