This tag in autodocs/window_cl mentions 'struct IEvent'. I can't find its specifications anywhere.
WINDOW_InputEvent (struct IEvent *)
Pointer to a "fake" input event which is valid only
immediately after receiving WHMI_RAWKEY. This provides all
the additional information suitable for you to call
Defaults to NULL.
Applicability is (OM_GET)
Anyone any idea?
I guess they mean struct InputEvent (that's what MapRawKey expects). It's defined in devices/inputevent.h
