Are you talking about logical ids (the one given by hwloc) or physical/OS ids (the one given by the OS and possibly in strange order) ? You should avoid using physical ids, but...
If logical, you can hwloc_get_obj_by_type() to get the corresponding object, then use its ->cpuset. If physical, you just need a cpuset that contains the bit corresponding to this id. You can use hwloc_bitmap_only(set, <id>) to reset a (previously allocated) cpuset to nothing but this id.
