13*5c2921b0SApple OSS Distributions<dt> <var>task</var>
14*5c2921b0SApple OSS Distributions<dd>
15*5c2921b0SApple OSS Distributions[in task send right]
16*5c2921b0SApple OSS DistributionsThe port for the task to be assigned.

18*5c2921b0SApple OSS Distributions<dd>
19*5c2921b0SApple OSS Distributions[in scalar]
20*5c2921b0SApple OSS DistributionsTrue if this assignment should apply as well to the threads
21*5c2921b0SApple OSS Distributionswithin the task.

23*5c2921b0SApple OSS Distributions<h3>DESCRIPTION</h3>
24*5c2921b0SApple OSS Distributions<p>
25*5c2921b0SApple OSS DistributionsThe <strong>task_assign_default</strong> function assigns <var>task</var> to the
26*5c2921b0SApple OSS Distributionsdefault processor set.
27*5c2921b0SApple OSS DistributionsAfter the assignment is completed, newly created threads within
28*5c2921b0SApple OSS Distributionsthis task will be
29*5c2921b0SApple OSS Distributionsassigned to this processor set.  Any previous assignment of the
30*5c2921b0SApple OSS Distributionstask is nullified.
31*5c2921b0SApple OSS Distributions<p>
32*5c2921b0SApple OSS DistributionsIf <var>assign_threads</var> is <strong>TRUE</strong>, existing threads within the
33*5c2921b0SApple OSS Distributionstask will also be assigned to the processor set.
34*5c2921b0SApple OSS Distributions<h3>NOTES</h3>
35*5c2921b0SApple OSS Distributions<p>
36*5c2921b0SApple OSS DistributionsThis variant of <strong>task_assign</strong> exists because the control
37*5c2921b0SApple OSS Distributionsport for the default
38*5c2921b0SApple OSS Distributionsprocessor set is privileged, and therefore not available to most tasks.
39*5c2921b0SApple OSS Distributions<h3>RETURN VALUES</h3>
40*5c2921b0SApple OSS Distributions<p>
41*5c2921b0SApple OSS DistributionsOnly generic errors apply.
