       rt_get_time - get the current time



WARNING

       This is RTL v1.x compatibility function. Please do not use

SYNOPSIS

       #define MODULE
       #include <linux/module.h>
       #include <linux/kernel.h>
       #include <linux/version.h>
       #include <linux/errno.h>
       #include <linux/rt_sched.h>

       RTIME rt_get_time(void);


DESCRIPTION

       rt_get_time returns the number of  real-time  clock  ticks
       since  system  bootup.   This is primarily helpful in con­
       junction with the defined constant RT_TICKS_PER_SECOND for
       scheduling  real-time tasks.  For example, a time interval
       of 100 msecs could be referred to as

        RTIME intvl = (RT_TICKS_PER_SECOND / 10);

       Then, for example,

        rt_task_make_periodic(&mytask, rt_get_time() + 5 * intvl,
       intvl);

       would  schedule mytask to run at 100 msec intervals start­
       ing 500 msec from the present time.


RETURN VALUE

       The number of clock ticks  since  system  bootup  time  is
       returned.


ERRORS

       None.
