#define PIO_KEYMAPENT _IOW('k', 11, keyarg_t)
Get/Set Keyboard Translation Table Entry.
They can be retrieved and changed individually.
keyarg_t == struct keyarg
struct keyarg {
u_short keynum; // the scancode, i.e. The index in curre
nt map. NOTE: the scancode here is not the meaning of PC Hardware based scan
code.
struct keyent_t key; // The value
};
Please refer to the explanation of GIO_KEYMAP/PIO_KEYMAP section for
the type struct keyent_t. The meaning is obvious now.
