NAME
rt_task_init - create a real-time task
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/rtf.h>
int rt_task_init(RT_TASK * task, void (*fn)(int data), int
data, int stack_size, int priority);
DESCRIPTION
rt_task_init creates a real-time task. task is a struc
ture the space for which must be provided by the applica
tion. task must be present during the lifetime of the
real-time task; thus it cannot be an automatic 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_LOW
EST_PRIORITY.
The newly created real-time task is initially dormant. It
is normally made active by a call to rt_task_make_peri
odic.
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 real-time
task.
