In such situations, SimGrid allows to write your protocol in your C
file, and the events to react to in a separate text file. Declare a
function handling each of the events that you want to accept in your
-trace files, register them using #MSG_action_register in your main,
+trace files, register them using #xbt_replay_action_register in your main,
and then use #MSG_action_trace_run to launch the simulation. You can
either have one trace file containing all your events, or a file per
simulated process.
