<h2>task_assign_default</h2>
<hr>
<p>
<strong>Function</strong> - Assign a task to the default processor set.
<h3>SYNOPSIS</h3>
<pre>
<strong>kern_return_t   task_assign_default</strong>
                <strong>(task_t</strong>                                    <var>task</var>,
                 <strong>boolean_t</strong>                       <var>assign_threads</var><strong>);</strong>
</pre>
<h3>PARAMETERS</h3>
<dl>
<dt> <var>task</var> 
<dd>
[in task send right]
The port for the task to be assigned.
<dt> <var>assign_threads</var> 
<dd>
[in scalar]
True if this assignment should apply as well to the threads 
within the task.
</dl>
<h3>DESCRIPTION</h3>
<p>
The <strong>task_assign_default</strong> function assigns <var>task</var> to the
default processor set.
After the assignment is completed, newly created threads within
this task will be 
assigned to this processor set.  Any previous assignment of the
task is nullified. 
<p>
If <var>assign_threads</var> is <strong>TRUE</strong>, existing threads within the 
task will also be assigned to the processor set.
<h3>NOTES</h3>
<p>
This variant of <strong>task_assign</strong> exists because the control
port for the default
processor set is privileged, and therefore not available to most tasks.
<h3>RETURN VALUES</h3>
<p>
Only generic errors apply.
