I have a process code, and i want to send a 'die' question to kill it. But i want to make sure that every time the kill message is prioritized, so if there is one - the process will die immediately.
receive
die -> dead;
after
0 -> receive
Message -> do_something(Message)
after
0 -> func(NewX)
end
end.
With your code, you're busy-waiting, you can do something like:
func(X) ->
receive % This checks the whole mailbox for 'die'
die -> dead;
after 0 -> % No 'die' message in mailbox, process the next Message whenever it arrives
receive % This checks only the next Message in the mailbox
die -> dead;
Message -> func(do_something(X, Message))
end
end.
