12*42e22086SApple OSS Distributions<dl>
13*42e22086SApple OSS Distributions<dt> <var>task</var>
14*42e22086SApple OSS Distributions<dd>
15*42e22086SApple OSS Distributions[in task send right]
16*42e22086SApple OSS DistributionsThe port for the task to be assigned.
17*42e22086SApple OSS Distributions<dt> <var>assign_threads</var>
18*42e22086SApple OSS Distributions<dd>
19*42e22086SApple OSS Distributions[in scalar]
20*42e22086SApple OSS DistributionsTrue if this assignment should apply as well to the threads
21*42e22086SApple OSS Distributionswithin the task.

23*42e22086SApple OSS Distributions<h3>DESCRIPTION</h3>
24*42e22086SApple OSS Distributions<p>
25*42e22086SApple OSS DistributionsThe <strong>task_assign_default</strong> function assigns <var>task</var> to the
26*42e22086SApple OSS Distributionsdefault processor set.
27*42e22086SApple OSS DistributionsAfter the assignment is completed, newly created threads within
28*42e22086SApple OSS Distributionsthis task will be
29*42e22086SApple OSS Distributionsassigned to this processor set.  Any previous assignment of the
30*42e22086SApple OSS Distributionstask is nullified.
31*42e22086SApple OSS Distributions<p>
32*42e22086SApple OSS DistributionsIf <var>assign_threads</var> is <strong>TRUE</strong>, existing threads within the
33*42e22086SApple OSS Distributionstask will also be assigned to the processor set.
34*42e22086SApple OSS Distributions<h3>NOTES</h3>
35*42e22086SApple OSS Distributions<p>
36*42e22086SApple OSS DistributionsThis variant of <strong>task_assign</strong> exists because the control
37*42e22086SApple OSS Distributionsport for the default
38*42e22086SApple OSS Distributionsprocessor set is privileged, and therefore not available to most tasks.
39*42e22086SApple OSS Distributions<h3>RETURN VALUES</h3>
40*42e22086SApple OSS Distributions<p>
41*42e22086SApple OSS DistributionsOnly generic errors apply.
