33 These are used internally either to the application or the kernel. The
34 same event is used for both Command and Information events.

37 gii_cmd_event is the basic structure for evCommand and evInformation
38 events. It may need to be casted to some other structure (depending on
39 code) to access the data.
40
42 code The command or request code.
43
44
45 data Provides raw access to the device and/or command specific data.
46 The recipient must not store references to the data. If the data
47 information is needed afterwards, copy it!

51 One use of evCommand is to convey some capabilities of a GII device,
52 via the GII_CMDCODE_GETDEVINFO command code.
