The function uses a register available in most modern CPUs to re‐
turn  a  value  that is monotonically increasing inside each CPU.
On SMP systems, there will be a number of separate monotonic  se‐
quences,  one for each CPU running.  The value in the SMP case is
selected from one of these sequences, dependent on which CPU  was
scheduled  to  service  the  request.   The speed and the maximum
value of each counter is CPU-dependent.  Some CPUs (such  as  the
80486) do not have such a register, so on these platforms returns
a (monotonic) combination of numbers represented by the structure
returned  by  The  and processors use the register.  The function
