+<h2>processor_set_policy_control</h2>
+<hr>
+<p>
+<strong>Function</strong> - Set target processor set's scheduling policy state.
+<h3>SYNOPSIS</h3>
+<pre>
+<strong>kern_return_t processor_set_policy_control</strong>
+ <strong>(processor_set_t</strong> <var>processor_set_control</var>,
+ <strong>processor_set_flavor_t</strong> <var>flavor</var>,
+ <strong>processor_set_info_t</strong> <var>policy_info</var>,
+ <strong>mach_msg_type_number_t*</strong> <var>policy_info_count</var>,
+ <strong>boolean_t</strong> <var>change_tasks_threads</var><strong>);</strong>
+</pre>
+<h3>PARAMETERS</h3>
+<dl>
+<dt> <var>processor_set_control</var>
+<dd>
+[in processor-set-control send right]
+A processor set control port.
+<dt> <var>flavor</var>
+<dd>
+[in scalar]
+The type of policy change to make.
+<dl>
+<dt> <strong>PROCESSOR_SET_TIMESHARE_DEFAULT</strong>
+<dd>
+Change the base attributes for the timeshare scheduling
+policy, making timeshare the default policy. The structure is
+<strong>policy_timeshare_base</strong>.
+<dt> <strong>PROCESSOR_SET_FIFO_DEFAULT</strong>
+<dd>
+Change the base attributes for the FIFO (first-in, first-out)
+scheduling policy, making FIFO the default policy. The
+structure is <strong>policy_fifo_base</strong>.
+<dt> <strong>PROCESSOR_SET_RR_DEFAULT</strong>
+<dd>
+Changed the base attributes for the round-robin scheduling
+policy, making round robin the default policy. The structure is
+<strong>policy_rr_base</strong>.
+<dt> <strong>PROCESSOR_SET_TIMESHARE_LIMITS</strong>
+<dd>
+Change the limits on the allowed timeshare policy attributes.
+The structure is defined by <strong>policy_timeshare_limit</strong>.
+<dt> <strong>PROCESSOR_SET_RR_LIMITS</strong>
+<dd>
+Change the limits on the allowed round robin policy
+attributes. The structure is defined by <strong>policy_rr_limit</strong>.
+<dt> <strong>PROCESSOR_SET_FIFO_LIMITS</strong>
+<dd>
+Change the limits on the allowed first-in, first-out policy
+attributes. The structure is defined by <strong>policy_fifo_limit</strong>.
+<dt> <strong>PROCESSOR_SET_ENABLED_POLICIES</strong>
+<dd>
+Change the set of enabled policies. The data is a bit-vector.
+</dl>
+<dt> <var>policy_info</var>
+<dd>
+[in structure]
+The relevant policy information.
+<dt> <var>policy_info_count</var>
+<dd>
+[in scalar]
+The size of the buffer (in natural-sized units).
+<dt> <var>change_tasks_threads</var>
+<dd>
+[in scalar]
+If true, any assigned task or thread whose policy is no
+longer enabled or whose scheduling attributes exceed the current limits will
+have their limits adjusted or their policy set to the default as
+appropriate.
+</dl>
+<h3>DESCRIPTION</h3>
+<p>
