+@code{@value{RPREFIX}INVALID_NUMBER} - the affinity set buffer is too small for

+
+@subheading DESCRIPTION:
+
+Returns the processor set owned by the scheduler in @code{cpuset}.  A set bit
+in the processor set means that this processor is owned by the scheduler and a
+cleared bit means the opposite.
