12*a1e26a70SApple OSS Distributions<dl>
13*a1e26a70SApple OSS Distributions<dt> <var>task</var>
14*a1e26a70SApple OSS Distributions<dd>
15*a1e26a70SApple OSS Distributions[in task send right]
16*a1e26a70SApple OSS DistributionsThe port for the task to be assigned.
17*a1e26a70SApple OSS Distributions<dt> <var>assign_threads</var>
18*a1e26a70SApple OSS Distributions<dd>
19*a1e26a70SApple OSS Distributions[in scalar]
20*a1e26a70SApple OSS DistributionsTrue if this assignment should apply as well to the threads
21*a1e26a70SApple OSS Distributionswithin the task.

23*a1e26a70SApple OSS Distributions<h3>DESCRIPTION</h3>
24*a1e26a70SApple OSS Distributions<p>
25*a1e26a70SApple OSS DistributionsThe <strong>task_assign_default</strong> function assigns <var>task</var> to the
26*a1e26a70SApple OSS Distributionsdefault processor set.
27*a1e26a70SApple OSS DistributionsAfter the assignment is completed, newly created threads within
28*a1e26a70SApple OSS Distributionsthis task will be
29*a1e26a70SApple OSS Distributionsassigned to this processor set.  Any previous assignment of the
30*a1e26a70SApple OSS Distributionstask is nullified.
31*a1e26a70SApple OSS Distributions<p>
32*a1e26a70SApple OSS DistributionsIf <var>assign_threads</var> is <strong>TRUE</strong>, existing threads within the
33*a1e26a70SApple OSS Distributionstask will also be assigned to the processor set.
34*a1e26a70SApple OSS Distributions<h3>NOTES</h3>
35*a1e26a70SApple OSS Distributions<p>
36*a1e26a70SApple OSS DistributionsThis variant of <strong>task_assign</strong> exists because the control
37*a1e26a70SApple OSS Distributionsport for the default
38*a1e26a70SApple OSS Distributionsprocessor set is privileged, and therefore not available to most tasks.
39*a1e26a70SApple OSS Distributions<h3>RETURN VALUES</h3>
40*a1e26a70SApple OSS Distributions<p>
41*a1e26a70SApple OSS DistributionsOnly generic errors apply.
