Manual Reference Pages  -  GETNANOUPTIME (9)

NAME

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

SYNOPSIS


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