Get gen_fsm PID

I start gen_fsm:

start_link() ->
     gen_fsm:start_link({global, ?MODULE}, [],
                   []).

How can i get it's P开发者_JS百科ID?

Thank you.

If you check the documentation for gen_fsm:start_link/3 you'll see that it returns {ok, Pid}.

You can either get it as the result of gen_fsm:start_link/3 or since it is a registered process using whereis(nameofprocess).
