Re: [Haskell-cafe] [help] Program immplementing an alarm

Thanks! But, when trying to implement your solution, I recalled hWaitForInput and used it to implement the alarm. Anyway, thanks, probably I will need that for other programas. Antonio

The getLine function ties up stdin. So the system function isn't able to proceed until getLine completes, even when it is in another thread.

Try using System.Process.runInteractiveProcess instead of system. Don't forget to call waitForProcess on the process handle when you are finished, or you will be left with a zombie.

Hope this helps, Yitz
