MICROUPTIME(9)           BSD Kernel Developer's Manual          MICROUPTIME(9)

NAME
     binuptime, getbinuptime, microuptime, getmicrouptime, nanouptime,
     getnanouptime, sbinuptime, getsbinuptime — get the time elapsed since
     boot

SYNOPSIS
     #include <sys/time.h>

     void
     binuptime(struct bintime *bt);

     void
     getbinuptime(struct bintime *bt);

     void
     microuptime(struct timeval *tv);

     void
     getmicrouptime(struct timeval *tv);

     void
     nanouptime(struct timespec *ts);

     void
     getnanouptime(struct timespec *tsp);

     sbintime_t
     sbinuptime(void);

     sbintime_t
     getsbinuptime(void);

DESCRIPTION
     The binuptime() and getbinuptime() functions store the time elapsed since
     boot as a struct bintime at the address specified by bt.  The
     microuptime() and getmicrouptime() functions perform the same utility,
     but record the elapsed time as a struct timeval instead.  Similarly the
     nanouptime() and getnanouptime() functions store the elapsed time as a
     struct timespec.  The sbinuptime() and getsbinuptime() functions return
     the time elapsed since boot as a sbintime_t.

     The binuptime(), microuptime(), nanouptime(), and sbinuptime() functions
     always query the timecounter to return the current time as precisely as
     possible.  Whereas getbinuptime(), getmicrouptime(), getnanouptime(), and
     getsbinuptime() functions are abstractions which return a less precise,
     but faster to obtain, time.

     The intent of the getbinuptime(), getmicrouptime(), getnanouptime(), and
     getsbinuptime() functions is to enforce the user's preference for timer
     accuracy versus execution time.
