PFND3DDDI_SETPRIORITY callback function (d3dumddi.h)
The SetPriority function sets the eviction-from-memory priority for a managed texture.
Syntax
PFND3DDDI_SETPRIORITY Pfnd3dddiSetpriority;
HRESULT Pfnd3dddiSetpriority(
HANDLE hDevice,
const D3DDDIARG_SETPRIORITY *unnamedParam2
)
{...}
Parameters
hDevice
A handle to the display device (graphics context).
unnamedParam2
pData [in]
A pointer to a D3DDDIARG_SETPRIORITY structure that specifies the priority level to set for the managed texture.
Return value
SetPriority returns one of the following values:
| Return code | Description |
|---|---|
| S_OK | The priority level is successfully set. |
| E_INVALIDARG | Parameters were validated and determined to be incorrect. |
Remarks
The Microsoft Direct3D runtime calls SetPriority to set the priority level for a resource. The user-mode display driver should translate the resource handle that is supplied in the hResource member of the D3DDDIARG_SETPRIORITY structure that is pointed to by pData to an allocation handle. After the driver makes this translation, the driver should pass the resulting handle in a call to the pfnSetPriorityCb function.
