static inline hwloc_obj_t hwloc_get_first_largest_obj_inside_cpuset | ( | hwloc_topology_t | topology, |

) | [static] |
Get the first largest object included in the given cpuset set
.
set
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.

Return the number of objects at depth depth

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
.
