The way I do it is simple, provided the keystrokes are being read from the
console.  I wrote a little function called clearkbd(), which uses the
function ConMayGetChar() found in the RKM Libraries manual.  It looks like
this:


char inkey()  /* get a keypress, or return 0 if no key has been pressed */
{
char key;
key = ConMayGetChar(consoleReadPort, consoleReadMsg, &keybuffer[0]);
return key;
}

void clearkbd()  /* clear out the keyboard buffer */
{
char key;
while ((key = inkey()) != '\0'); 
}


clearkbd() is called to clear out all unused keystrokes from the keyboard
buffer before getting the next keystroke.  The effect of this is that
auto-repeats will only go as fast as my program gets characters.
