pfnReclaimAllocations3Cb is called by the user mode driver to reclaim video memory allocations that were previously offered for reuse.
Syntax
PFND3DDDI_RECLAIMALLOCATIONS3CB Pfnd3dddiReclaimallocations3cb;
HRESULT Pfnd3dddiReclaimallocations3cb(
HANDLE hDevice,
D3DDDICB_RECLAIMALLOCATIONS3 *unnamedParam2
)
{...}
Parameters
hDevice
A handle to the display device.
unnamedParam2
pData [in, out]
A pointer to a D3DDDICB_RECLAIMALLOCATIONS3 structure that defines the allocations to reclaim. The previously used discarded array is replaced by a pResults member in this iteration.
Return value
Returns one of the following values.
Return code | Description |
---|---|
S_OK | The allocations were successfully reclaimed. |
E_INVALIDARG | An invalid parameter was supplied. |
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. Note: If this error code is returned, the driver's calling function (typically the pfnReclaimResources routine) must return this error code to the Direct3D runtime. |
