kii_register_input() is typically called when a new input driver is loaded.

kii_error_t kii_register_input(

 /* Comment: the focus to register to */
 kii_u_t focus,

 /* Comment: preinitialized data about the input to register */
 kii_input_t *dev
);

kii_unregister_input() is typically called

void kii_unregister_input(

 /* Comment: the input to unregister from its focus */
 kii_input_t *dev
);
