and whose parent is not.This is convenient for iterating over all largest objects within a CPU set by doing a loop getting the first largest object and clearing its CPU set from the remaining CPU set.

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
.
