-DIRECTIVE STATUS CODES:

-    The count of processors in the system that can be run. The value returned
-    is the highest numbered processor index of all processors available to the
-    application (if a scheduler is assigned) plus one.
-
-DESCRIPTION:
-    In uniprocessor configurations, a value of one will be returned.
-
-    In SMP configurations, this returns the value of a global variable set
-    during system initialization to indicate the count of utilized processors.
-    The processor count depends on the physically or virtually available
-    processors and application configuration.  The value will always be less
-    than or equal to the maximum count of application configured processors.
