I am trying to do non-delay mode read from cin, i.e.
        char ch;
        ...
        while( cin.getch(ch) )
        {
                ...
        }
I want getch to return whenever there is a char typed (not wait till
a newline is seen).

How do I do this? I am using linux if it matters.

thanks,

----RICH
