Greetings,
Suppose that you have a process running like this:
loop( State ) ->
receive
normal ->
New_state = new_state( State ),
loop( New_state )
_ -> ok
end.
You could add a forking like this:
loop( State ) ->
receive
normal ->
loop( State )
fork ->
spawn( fun() -> loop(State) end ),
loop( State )
_ -> ok
end.
