erlang - Wait for Node.connect before using :global.whereis_name -


i have following function:

  def join(id)     if node.connect(:"#{id}@127.0.0.1")       send :global.whereis_name(id), {:join, id}     end   end 

i receive error:

(argumenterror) argument error                :erlang.send(:undefined, ... 

which assume because node.connect gathering of information , when call :global.whereis_name has not finished yet. if throw in :timer.sleep(1000) sure enough don't error. there more elegant solution? repeat :global.whereis_name until successful or timeout reached.

edit:

i should mention have node registered name id.

you :global.sync() before :global.whereis_name(id)
