What constitute the standalone code ?

in fact, to port the simulator, I only had to implement the following:
sim_engine_run ()
sim_open ()
sim_create_inferior ()

All the above functions are both used when the sim is running
"standalone" or by "GDB".

Is there another function I can define that will only be used when the
sim is running "standalone" ?
