View the official Windows Driver Kit DDI referenceNo description available.
Inserts a signal on the specified synchronization objects in the specified context direct memory access (DMA) stream. Used by WDDM 1.2 and later user-mode display drivers.
hDeviceA handle to a display device (that is, the graphics context).
unnamedParam2pData [in]
A pointer to a D3DDDICB_SIGNALSYNCHRONIZATIONOBJECT2 structure that describes the synchronization objects and context DMA stream that signaling is set up on.
Returns one of the following values:
| Return code | Description |
|---|---|
| S_OK | The signaling was successfully set up. |
| E_INVALIDARG | Parameters were validated and determined to be incorrect. |
This function might also return other HRESULT values.
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:
The pfnSignalSynchronizationObject2Cb function submits a signal command to the command stream of all Microsoft Direct3D contexts that are specified by the hContext and BroadcastContext members of the D3DDDICB_SIGNALSYNCHRONIZATIONOBJECT2 structure. The synchronization objects are signaled only when all submitted signal commands are processed.
If synchronization objects are of type D3DDDI_FENCE (where D3DDDI_SYNCHRONIZATIONOBJECTINFO2.Type = D3DDDI_FENCE), they must be submitted only one at a time, and D3DDDICB_SIGNALSYNCHRONIZATIONOBJECT2.ObjectCount must have a value of 1.
