Called by the Microsoft Direct3D runtime to reclaim video memory resources that it previously offered for reuse.
Syntax
PFND3DDDI_RECLAIMRESOURCES Pfnd3dddiReclaimresources;
HRESULT Pfnd3dddiReclaimresources(
HANDLE hDevice,
const D3DDDIARG_RECLAIMRESOURCES *unnamedParam2
)
{...}
Parameters
hDevice
A handle to the display device (graphics context).
unnamedParam2
pData [in]
A pointer to a D3DDDIARG_RECLAIMRESOURCES structure that defines the video memory resources to reclaim.
Return value
Returns one of the following values:
| Return code | Description |
|---|---|
| S_OK | The video memory resources were successfully reclaimed. This error code is returned if the driver does not need to call the pfnReclaimAllocationsCb function. |
| E_INVALIDARG | An invalid parameter was supplied. This error code is returned if the driver calls the pfnReclaimAllocationsCb function and that function returns E_INVALIDARG. |
| D3DDDIERR_DEVICEREMOVED | The video memory manager or display miniport driver could not complete the operation because either a Plug and Play (PnP) Stop event or a Timeout Detection and Recovery (TDR) event occurred. This error code is returned if the driver calls the pfnReclaimAllocationsCb function and that function returns D3DDDIERR_DEVICEREMOVED. Note: If this error code is returned, the driver's calling function (typically the ReclaimResourcesDXGI routine) must return this error code to the Direct3D runtime. |
