WARNING
This is RTL v1.x compatibility function. Please do not use
it for new programs.
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.
