PFND3DDDI_EVICTCB callback function (d3dumddi.h)
pfnEvictCb is used to instruct the OS to decrement the residency reference count. Once this count reaches zero, it will remove the allocation from the device residency list.
Syntax
PFND3DDDI_EVICTCB Pfnd3dddiEvictcb;
HRESULT Pfnd3dddiEvictcb(
HANDLE hDevice,
D3DDDICB_EVICT *unnamedParam2
)
{...}
Parameters
hDevice
A handle to the display device.
unnamedParam2
pData [in, out]
A pointer to a D3DDDICB_EVICT structure that describes the memory pages to evict.
Return value
If this callback function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
Remarks
Once the eviction request is queued, it is illegal to access the underlying allocation as the allocation may be evicted at anytime from there on at the operating system discretion.
