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.
