processor_set_max_priority
is used to set the
maximum priority for a processor set. The priority of a processor set
is used only for newly created threads (thread's maximum priority is set
to processor set's) and the assignment of threads to the set (thread's
maximum priority is reduced if it exceeds the set's maximum priority,
thread's priority is similarly reduced). processor_set_max_priority
changes this priority. It also sets the maximum priority of all threads
assigned to the processor set to this new priority if
change_threads is TRUE
. If this maximum priority is less
than the priorities of any of these threads, their priorities will also
be set to this new value.
This function returns KERN_SUCCESS
if the call succeeded and
KERN_INVALID_ARGUMENT
if processor_set is not a processor
set or priority is not a valid priority.
