NAME
       kdk_rti_get_uptime - <?><?><?><?><?><?><?><?><?><?>

SYNOPSIS
       #include <libkyrtinfo.h>

       extern int kdk_rti_get_uptime(unsigned int *day, unsigned int *hour, unsigned int *min, unsigned int *sec);

       Link with -lkyrtinfo.

Detailed Description
       The main function of the interface is to obtain the operating system
       boot time.

       The argument day is the number of days.  The argument hour is the
       number of hours.  The argument min is the number of minutes.  The
       argument sec is the number of seconds.

RETURN VALUE
