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.
