rtapi_task_new − create a realtime task
int rtapi_task_new(void (*taskcode)(void*), void *arg, |
int prio, unsigned long stacksize, int uses_fp)
int rtapi_task_delete(int task_id) |
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
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.
Call only from within init/cleanup code, not from realtime tasks.
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.
