 oh yes, much more complicated, you have to use #include <curses.h>
rather than #include <conio.h> -- but the question as I understand
it was how to impliment "hot" keys under DOS using C which is not
portably done under DOS by reading scan codes -- but is portably
done by using pccurses or a series of #define KEY_UP etc ...

 union k {
	char ch[2];
	unsigned i;
	} key;
 ...
 if(!key.ch[0]) { /* it's a 'hot' one */
	switch(key.ch[1]){
		...
	
	}
