PFND3DDDI_RECLAIMALLOCATIONSCB callback function

Description

Called by the user-mode display driver to reclaim video memory allocations that were previously offered for reuse.

Parameters

`hDevice`

A handle to the display device (graphics context).

`unnamedParam2`

pData [in]

A pointer to a D3DDDICB_RECLAIMALLOCATIONS structure that defines the allocations to reclaim.

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.
