I was experimenting with this yesterday evening, and it turns out to be
really trivial! This little function will return how far the mouse has
moved since the last time you called it...


#include <dpmi.h>

/* get_mouse_mickeys:
 *  Measures the mickey count (how far the mouse has moved since the 
 *  last call to this function).
 */
void get_mouse_mickeys(int *mickeyx, int *mickeyy)
{
   __dpmi_regs r;

   r.x.ax = 11;
   __dpmi_int(0x33, &r);

   *mickeyx = (signed short)r.x.cx;
   *mickeyy = (signed short)r.x.dx;
}
