NAME
binuptime, getbinuptime, microuptime, getmicrouptime, nanouptime, getnanouptime -- 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); 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 binuptime(), microuptime(), and nanouptime() functions always query the timecounter to return the current time as precisely as possible. Whereas getbinuptime(), getmicrouptime(), and getnanouptime() functions are abstractions which return a less precise, but faster to obtain, time. The intent of the getbinuptime(), getmicrouptime(), and getnanouptime() functions is to enforce the user's preference for timer accuracy ver- sus execution time. SEE ALSO
