.TH rtapi_task_new "3rtapi" "2006-10-12" "LinuxCNC Documentation" "RTAPI"
.SH NAME
rtapi_task_new \- create a realtime task
.SH SYNTAX
.HP
int rtapi_task_new(void (*\fItaskcode\fR)(void*), void *\fIarg\fR,
int \fIprio\fR, unsigned long \fIstacksize\fR, int \fIuses_fp\fR)
.HP
int rtapi_task_delete(int \fItask_id\fR)
.HP
.SH ARGUMENTS
.IP \fItaskcode\fR
A pointer to the function to be called when the task is started
.IP \fIarg\fR
An argument to be passed to the \fItaskcode\fR function when the task is
started
.IP \fIprio\fR
A task priority value returned by \fBrtapi_prio_xxxx\fR
.IP \fIuses_fp\fR
A flag that tells the OS whether the task uses floating point or not.
.IP \fItask_id\fR
A task ID returned by a previous call to \fBrtapi_task_new\fR
.SH DESCRIPTION
\fBrtapi_task_new\fR creates but does not start a realtime task. The task is
created in the "paused" state. To start it, call either \fBrtapi_task_start\fR
for periodic tasks, or \fBrtapi_task_resume\fR for free-running tasks.
.SH REALTIME CONSIDERATIONS
Call only from within init/cleanup code, not from realtime tasks.
.SH 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.
.SH SEE ALSO
\fBrtapi_prio(3rtapi)\fR, \fBrtapi_task_start(3rtapi)\fR, \fBrtapi_task_wait(3rtapi)\fR, \fBrtapi_task_resume(3rtapi)
