Probably not, look at this remark from the modules documentation:
These functions are intended for interactive use in the Erlang shell only. The module prefix can be omitted.
Also :c.flush/0 shouldn’t return a tuple or a list (I assume thats what you are talking about when saying “array”), it should just return the atom :ok.
If you really want to flush the mailbox, you can implement this really easily:
def flush() do
receive do
_ -> flush()
after
0 -> :ok
end
end
You can easily extend it to actually print or return the “flushed” messages if you need to.
