NAME

rtapi_task_new − create a realtime task

SYNTAX

int rtapi_task_new(void (*taskcode)(void*), void *arg,

int prio, unsigned long stacksize, int uses_fp)

int rtapi_task_delete(int task_id)

ARGUMENTS

taskcode

A pointer to the function to be called when the task is started

	arg		An argument to be passed to the taskcode function when the task is started
	prio		A task priority value returned by rtapi_prio_xxxx

uses_fp

A flag that tells the OS whether the task uses floating point or not.

task_id

A task ID returned by a previous call to rtapi_task_new

DESCRIPTION

rtapi_task_new creates but does not start a realtime task. The task is created in the "paused" state. To start it, call either rtapi_task_start for periodic tasks, or rtapi_task_resume for free-running tasks.

REALTIME CONSIDERATIONS

Call only from within init/cleanup code, not from realtime tasks.

RETURN VALUE

On success, returns a positive integer task ID. This ID is used for all subsequent calls that need to act on the task. On failure, returns an RTAPI status code.
