View the official Windows Driver Kit DDI referenceNo description available.
The pfnCreateSynchronizationObjectCb function creates a synchronization object that a device context can signal and wait for.
hDeviceA handle to the display device (that is, the graphics context) that will own the synchronization object that pfnCreateSynchronizationObjectCb creates.
unnamedParam2pData [in, out]
A pointer to a D3DDDICB_CREATESYNCHRONIZATIONOBJECT structure that describes the synchronization object to create.
pfnCreateSynchronizationObjectCb returns one of the following values:
| Return code | Description |
|---|---|
| S_OK | The synchronization object was successfully created. |
| E_OUTOFMEMORY | pfnCreateSynchronizationObjectCb could not allocate memory that was required for it to complete. |
| E_INVALIDARG | Parameters were validated and determined to be incorrect. |
This function might also return other HRESULT values.
The pfnCreateSynchronizationObjectCb function returns a kernel-mode handle to the newly created synchronization object in the hSyncObject member of the D3DDDICB_CREATESYNCHRONIZATIONOBJECT structure that the pData parameter points to. The user-mode display driver passes this handle in calls to the following functions:
D3DDDICB_CREATESYNCHRONIZATIONOBJECT
pfnDestroySynchronizationObjectCb
pfnSignalSynchronizationObjectCb
pfnWaitForSynchronizationObjectCb
