PFND3DDDI_WAITFORSYNCHRONIZATIONOBJECT2CB callback function (d3dumddi.h)
Inserts a wait command for the specified synchronization objects in the specified context command stream. Used by Windows Display Driver Model (WDDM) 1.2 and later user-mode display drivers.
Syntax
PFND3DDDI_WAITFORSYNCHRONIZATIONOBJECT2CB Pfnd3dddiWaitforsynchronizationobject2cb;
HRESULT Pfnd3dddiWaitforsynchronizationobject2cb(
HANDLE hDevice,
const D3DDDICB_WAITFORSYNCHRONIZATIONOBJECT2 *unnamedParam2
)
{...}
Parameters
hDevice
A handle to a display device (that is, the graphics context).
unnamedParam2
pData [in]
A pointer to a D3DDDICB_WAITFORSYNCHRONIZATIONOBJECT2 structure that describes the synchronization objects and context DMA stream that are required to set up the wait.
Return value
Returns one of the following values:
| Return code | Description |
|---|---|
| S_OK | The wait was successfully set up. |
| E_INVALIDARG | Parameters were validated and determined to be incorrect. |
This function might also return other HRESULT values.
Remarks
The pfnCreateSynchronizationObject2Cb function returns a kernel-mode handle to the newly created synchronization object in the hSyncObject member of the D3DDDICB_CREATESYNCHRONIZATIONOBJECT2 structure that the pData parameter points to. The user-mode display driver passes this handle in calls to the following functions:
- pfnWaitForSynchronizationObject2Cb
