   You have to take that into account and construct your getkey
   function accordingly. In this example, you can pass a filter
   string, or NULL, and whether to wait or return immediately if
   no key has been pressed. The update_clock() routine should be
   separate so it may be called from various places, or not
   called if the display is one where it is not wanted.
   One could also make the call to update_clock() dependent
   upon a variable as well.
int getkey_clock(char *filter, int wait)
{
   int result = 0;
   do {
      if(kbhit())
      {
         result = (0 == (result = getch())) ? -getch() : result;
         if(filter && !strchr(filter, result))
            result = 0;
      }
      update_clock();
   }  while(!result && wait)
   return result;
}
