The keys have benn captured!!!!

If you want the character echoed to the screen, you should use getche(). It
works just like getch(), but automatically echoes to the screen.

OK, listen to me everybody.

I said I WILL implement OpenGl but I didn't say I was already implementing
it. Yes, I am programing some DOS code for my university and finally I have
the code right now, thanks to some of you and some other good stuff I found
on the net.

Some interesting aspects:

getchar() doesn't work fine but getch() does. However it's very dificult to
print on the screen the values this function retunrs, so I had to search for
the right codes for this keys on the keyboard and I'd like to share them
with all of you:

here is the code:


char c:

if ((c = getch()) == 27)
    // Escape key was pressed so do whatever you want
if (c ==  72)
  // up arrow key was pressed so do whatever you want
if (c ==  80)
  // down arrow key was pressed so do whatever you want
if (c ==  77)
  // right arrow key was pressed so do whatever you want
if (c ==  75)
  // left arrow key was pressed so do whatever you want
if (c ==  13)
  // ENTER key was pressed so do whatever you want



Hope somebody find this usefull (besides of me)
