Declaring the Loadable Module Configuration Entry Points

The _init(9E), _info(9E), and _fini(9E) routine names are not unique to any particular kernel module. You customize the behavior of these routines when you define them in your module, but the names of these routines are not unique. These three routines are declared in the modctl.h header file. You need to include the modctl.h header file in your dummy.c file. Do not declare these three routines in dummy.c.
