| Re: [erlang-questions] gproc and gen_event | |
| Of course, for a distributed pub/sub, you don't really need to turn on | |
| the distributed parts of gproc. Running a local gproc instance on each | |
| node, you can publish like so: | |
| publish(Event, Data) -> | |
| rpc:eval_everywhere( | |
| gproc, send, | |
| [{p, l, {?MODULE, Event}}, {?MODULE, Event, Data}]). |
