erlang: anything like name_for_pid()?

Is there a way t开发者_运维百科o get a registered name if you have a PID?

I'm assuming you want this for some kind of debugging/introspection purpose and not for general use in your code:

erlang:process_info(Pid, registered_name).

Gives you [] if the process doesn't have a locally registered name, and {registered_name, Name} if there is one.
