Concurrency in Functions and Messages

[Inswitch Solutions - Erlang Evaluation]

When a process is in receive state (receive -> ....), I understand that concurrency is managed by a queue in Erlang when other processes send messages to it.

I don't know how Erlang manages functions calls concurrency when
more than one process is calling the same function.
For example io:format(.....) called by two processes at the same time.

Does anyone know something about this ?

Thanks,
