I had a similar problem (was looking for an unbuffered get-character
function. Up to now I'm using getkey() of <pc.h> but
it has the drawback of mapping key combinations to values greater
than 255. So I wrote a wrapper that maps values above 255
to character (<256) combinations:

int getkbd()

{
  static int i_next=-1;
  int i;

  if (i_next != -1)
    {
      i=i_next;
      i_next=-1;
    }
  else
    {
      i=getkey();
      if (i>511)
        {
          i_next=i-512;
          i=27;
        }
      if (i>255)
        {
          i_next=i-256;
          i=0;
        }
    }
  return(i);
}

I'm not as happy with that solution as I should be.
I there a better solution?
