Concurrency in Functions and Messages

the called function is run in the context of the calling process. A module
is just a container for some code and it exports some functions. If you are
familiar with C, calling io:format is the same as calling printf.

Subject: Concurrency in Functions and Messages

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 ?
