SYNOPSIS
#define MODULE #include <linux/module.h> #include <linux/kernel.h> #include <linux/version.h> #include <linux/errno.h> #include <linux/rt_sched.h>
int rt_task_make_periodic(RT_TASK * task, RTIME start_time, RTIME period);
DESCRIPTION
rt_task_make_periodic marks a task, previously created with a call to rt_task_init, as ready for execution. The task will run at intervals specified by period; i.e., it will be marked for execution every period real-time clock ticks. The desired start time is specified by start_time; the first execution of the task will occur start_time clock ticks from the current time. If immediate execution is desired, the return value of rt_get_time can be used for start_time.
RETURN VALUE
On success, 0 is returned. On failure, a negative value is returned as described below.
ERRORS
