  It would be as correct as the user's OS (namely Win95) provides
  Since calling that API user wants (I guess) to estimate the time 
                                                 ========
  and this incorrect value may help him but  ENOSYS ?

  Anyway it can not be absolutely precise value for any system. There 
is some error anyway. This error will be large for Win95. For this 
case the 

                "REAL exact value" <= "supplied"

 and it will be not far from the real one if the user's system is 
 running a single process.

 Is it wrong ?
