1<h2>processor_set_max_priority</h2> 2<hr> 3<p> 4<strong>Function</strong> - Sets the maximum scheduling priority for a processor set. 5<h3>SYNOPSIS</h3> 6<pre> 7<strong>#include< mach/mach_host.h></strong> 8 9<strong>kern_return_t processor_set_max_priority</strong> 10 <strong>(processor_set_t</strong> <var>processor_set</var>, 11 <strong>int</strong> <var>priority</var>, 12 <strong>boolean_t</strong> <var>change_threads</var><strong>);</strong> 13</pre> 14<h3>PARAMETERS</h3> 15<dl> 16<dt> <var>processor_set</var> 17<dd> 18[in processor-set-control port] The control port for the processor set whose maximum scheduling priority is to be set. 19<dt> <var>priority</var> 20<dd> 21[in scalar] The new priority for the processor set. 22<dt> <var>change_threads</var> 23<dd> 24[in scalar] True if the maximum priority of existing threads assigned to this processor set should also be changed. 25</dl> 26<h3>DESCRIPTION</h3> 27<p> 28The <strong>processor_set_max_priority</strong> 29function sets the maximum scheduling <var>priority</var> for 30<var>processor_set</var>. The maximum <var>priority</var> of a 31processor set is used only when creating new threads. A new thread's 32maximum <var>priority</var> is set to that of its assigned processor 33set. When assigned to a processor set, a thread's maximum 34<var>priority</var> is reduced, if necessary, to that of its new 35processor set; its current <var>priority</var> is also reduced, as 36needed. Changing the maximum <var>priority</var> of a processor set 37does not affect the <var>priority</var> of the currently assigned 38threads unless <var>change_threads</var> is TRUE. If this 39<var>priority</var> change violates the maximum <var>priority</var> of 40some threads, their maximum priorities will be reduced to match. 41<h3>RETURN VALUES</h3> 42<p> 43Only generic errors apply. 44<h3>RELATED INFORMATION</h3> 45<p> 46Functions: 47<a href="thread_assign.html">thread_assign</a>. 48
