[erlang-questions] Ensure if a function/arity is exported from a module or not?

[Zabrane Mickael]

Hi guys,

What's the correct/best way to ensure that a module exports a certain function or not?

Lets say:
-module(foo).
-export([main/1]).
...

I need to know if module foo exports or not main/1 without having foo source code of course (only foo.beam is available).

Regards,
Zabrane
