       Be sure to see the figure in termsanddefs that shows a complete topology tree, including depths, child/sibling/cousin relationships, and an
       example of an asymmetric topology where one socket has fewer caches than its peers.

Function Documentation
   static inline hwloc_obj_t hwloc_get_ancestor_obj_by_depth (hwloc_topology_t topology, unsigneddepth, hwloc_obj_tobj) [static]
       Returns the ancestor object of obj at depth depth.

   static inline hwloc_obj_t hwloc_get_ancestor_obj_by_type (hwloc_topology_t topology, hwloc_obj_type_ttype, hwloc_obj_tobj) [static]
       Returns the ancestor object of obj with type type.

   static inline hwloc_obj_t hwloc_get_common_ancestor_obj (hwloc_topology_t topology, hwloc_obj_tobj1, hwloc_obj_tobj2) [static]
       Returns the common parent object to objects lvl1 and lvl2.

   static inline hwloc_obj_t hwloc_get_next_child (hwloc_topology_t topology, hwloc_obj_tparent, hwloc_obj_tprev) [static]
       Return the next child. If prev is NULL, return the first child.

   static inline hwloc_obj_t hwloc_get_next_obj_by_depth (hwloc_topology_ttopology, unsigneddepth, hwloc_obj_tprev) [static]
       Returns the next object at depth depth. If prev is NULL, return the first object at depth depth.

   static inline hwloc_obj_t hwloc_get_next_obj_by_type (hwloc_topology_ttopology, hwloc_obj_type_ttype, hwloc_obj_tprev) [static]
       Returns the next object of type type. If prev is NULL, return the first object at type type. If there are multiple or no depth for given
       type, return NULL and let the caller fallback to hwloc_get_next_obj_by_depth().

   static inline hwloc_obj_t hwloc_get_pu_obj_by_os_index (hwloc_topology_ttopology, unsignedos_index) [static]
       Returns the object of type HWLOC_OBJ_PU with os_index. Note:
	   The os_index field of object should most of the times only be used for pretty-printing purpose. Type HWLOC_OBJ_PU is the only case
	   where os_index could actually be useful, when manually binding to processors. However, using CPU sets to hide this complexity should
	   often be preferred.

   static inline hwloc_obj_t hwloc_get_root_obj (hwloc_topology_ttopology) [static]
       Returns the top-object of the topology-tree. Its type is typically HWLOC_OBJ_MACHINE but it could be different for complex topologies. This
       function replaces the old deprecated hwloc_get_system_obj().

   static inline int hwloc_obj_is_in_subtree (hwloc_topology_t topology, hwloc_obj_tobj, hwloc_obj_tsubtree_root) [static]
       Returns true if obj is inside the subtree beginning with subtree_root. Note:
	   This function assumes that both obj and subtree_root have a cpuset.
