I don't think there's any specific function for this - when I did
something similar, I wrote a little wrapper function something like
this: (dodgy pseudo code follows...)
void reset_timeout(void){
Fl::remove_timeout(...);
Fl::add_timeout(300, ...);
}
And called that *often*, whenever there was some user-interaction that
needed handling.
When the timeout did fire, it's callback function took me back to an
init screen.
I guess that's something like what you need?
Not elegant, but it did work...
