-#### WintunOpenAdapterDeviceObject()
-
-`HANDLE WintunOpenAdapterDeviceObject (WINTUN_ADAPTER_HANDLE Adapter)`
-
-Returns a handle to the adapter device object.

-**Parameters**
-
-- *Adapter*: Adapter handle obtained with WintunOpenAdapter or WintunCreateAdapter.
-
-**Returns**
-
-If the function succeeds, the return value is adapter device object handle. Must be released with CloseHandle. If the function fails, the return value is INVALID\_HANDLE\_VALUE. To get extended error information, call GetLastError.
