## NAME

           gethrtime - get high resolution time

## SYNOPSIS

           #include <rtl_time.h>

           hrtime_t gethrtime(void);

## DESCRIPTION

           This function is a non-portable Real-Time Linux extension.
           gethrtime returns the time in nanoseconds since the system
           bootup.  This  time is never reset or adjusted.  gethrtime
           always gives monotonically increasing values.  hrtime_t is
           a 64-bit signed integer.

           The HRTIME_INFINITY symbol represents the maximum possible
           value that gethrtime() could possibly return.  This  value
           will  be never reached during the execution of the system,
           and can be used to designate the infinitely distant moment
           in time.

## NOTES

           The  actual resolution of gethrtime is hardware-dependent.
           It is guaranteed to be better than 1 microsecond.
