It's no big deal, the following code shows the workaround I'm using, but
I still don't know why rawclock() always returns zero.  What am I doing
wrong?


-------------------


#include <stdio.h>
#include <time.h>
#include <dpmi.h>

main() {
__dpmi_regs r;
unsigned long t;

  printf("rawclock(): %d\n",rawclock() );  // Always returns 0; why?

  r.x.ax = 0;
  __dpmi_int( 0x1a, &r );
  t = r.x.cx << 16 | r.x.dx;
  printf("ticks via BIOS: %d\n", t );      // This works fine
}
