i want a class that when created, install a timer interupt using
allegro. below is a simplified version
of what i tried and doesn't work.


class foo
{
public:
  foo();
  void callback();

private:
  int counter;
};

foo::foo()
{
  LOCK_FUNCTION (callback);
  LOCK_VARIABLE (counter);
  install_int (callback, 100);
}

void foo::callback()
{
  counter++;
}
END_OF_FUNCTION (callback);
