What a strange place to post this message... As I haven"t seen it crossposted
elsewhere, I'll answer here.

The scanf(char*, ...) function doesn't appear to be defined in stdio.h.
But what would you expect scanf to do, if it worked ?
There is no keyboard on your Yaroze... and the way you get user input in a
videogame is very different than the way scanf works.

Scanf waits until it gets the input it's expecting. That means, nothing happens
until the user has typed in something. In a game, you'd rather look from time
to time (once each frame) which keys are on, whithout stopping the action.
Unless you're coding a text adventure game, that is.
So if you want to get input from the controllers, scanf, even if it was
implemented, wouldn't be useful. Now, what can you do ? Well, have a look at
the tutorials, or any source code that makes use of the controller ; you'll
quickly isolate the code that reads the controller keys (see on the Yaroze disc
: psx\quick\pad.c). As there are not many ways of doing this, the best thing
for you to do is to copy/paste it into your program.
Alternatively, look for controller libraries in members' pages.

Hope this helps,
pal.
