static |
Return the number of objects of type type included in CPU set set.
If no object for that type exists inside CPU set set, 0 is returned. If there are several levels with objects of that type inside CPU set set, -1 is returned.

static |
Return the next object at depth depth included in CPU set set.
If prev is NULL, return the first object at depth depth included in set. The next invokation should pass the previous return value in prev so as to obtain the next object in set.
