This is an RTLinux v1.x compatibility function. For new programs, please see pthread_make_periodic_np(3).

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 realtime 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.

On success, 0 is returned. On failure, a negative value is returned as described below.

-EINVAL

task does not refer to a valid RT_TASK structure.
