#define MODULE
#include <linux/module.h>

#include <linux/errno.h>
#include <linux/rtf.h>
#include <asm/rt_irq.h>
int rt_task_init(RT_TASK *task, void (*fn)(int data), int data, int stack_size, int priority);
WARNING
This is an RTLinux v1.x compatibility function. For new programs,
please see pthread_create(3).
DESCRIPTION
rt_task_init creates a realtime task. task is a structure the space
for which must be provided by the application. task must be present
during the lifetime of the realtime task; thus it cannot be an auto-
matic variable. fn is the entry point of the new task. The parent
task can send a one-integer value data to the new task.
stack_size is the size of the stack to be used by the new task, and
priority is the priority to be given the task. The highest priority is
1, while the lowest is RT_LOWEST_PRIORITY.
The newly created real-time task is initially dormant. It is normally
made active by a call to rt_task_make_periodic.
RETURN VALUE
On success, 0 is returned. On failure, a negative value is returned
as described below.
ERRORS
-EINVAL task is already in use by another task.
-ENOMEM space could not be allocated for the realtime task.
