I have following simple test code to try how to send messages between process.

The way I understand my code is :

1. I spawn 2 separate processes
2. Processes are executing functions where they should be awaiting a message
3. In parent process I send a message to each process
4. Processes should receive them and IO.puts message

What is happening is that nothing is in output and it looks as though program is executing but nothings happening. I have to cntrl+C out of it.

What am I doing wrong?

defmodule Test do
    def startGame() do
        hValue = 1
        dValue = 2

        parent = self()
        hPID = spawn humanTurn(hValue, parent)
        dPID = spawn dealerTurn(dValue, parent)

        send(hPID, {:parent, dValue})
        send(dPID, {:parent, dValue})
    end

    def dealerTurn(dValue, parent) do
        receive do
            {:parent, msg} -> IO.puts(msg)
        end
    end

    def humanTurn(hValue, parent) do
        receive do
            {:parent, msg} -> IO.puts(msg)
        end
    end

end
