Hello all,

           I was reading about how qemu uses vnc server to access the screen
of guest OS.While reading I came across function "key_event" called for key
processing in client-server interaction phase in file vnc.c. In "key_event"
function "do_key_event" function calls the function "kbd_put_keycode" whose
definition is as follows :

void kbd_put_keycode(int keycode)
{
    if (qemu_put_kbd_event) {
        qemu_put_kbd_event(qemu_put_kbd_event_opaque, keycode);
    }
}

In above fuction I didnt get the function definition for call
"qemu_put_kbd_event(qemu_put_kbd_event_opaque, keycode); " which is called
by function pointer and I also didnt get the significance of generic pointer
"qemu_put_kbd_event_opaque" . So please help in this regard.

Thanks,
Amey
