[in] NT handle for the shared fence object.

`hDevice`

[in] Device handle to open this fence object on.

`EngineAffinity`

[in] Defines the physical adapters where the GPU virtual address is mapped.

`Flags`

[in] A D3DDDI_SYNCHRONIZATIONOBJECT_FLAGS structure that identifies the attributes of the synchronization object.

`hSyncObject`

[out] Handle to the opened fence object.

`NativeFenceMapping`

[out] A D3DDDI_NATIVEFENCEMAPPING structure that contains process mapping information for the fence object.

`Reserved[32]`

Reserved for system use.
