## Detailed Description

## Function Documentation

## hwloc_get_child_covering_cpuset()

static hwloc_obj_t hwloc_get_child_covering_cpuset | ( | hwloc_topology_t | topology,
|  | hwloc_const_cpuset_t | set,
|  | hwloc_obj_t | parent
| ) |  |

inlinestatic

Get the child covering at least CPU set `set`.

Returns
  `NULL` if no child matches or if `set` is empty.

Note
  This function cannot work if parent does not have a CPU set (I/O or Misc objects).

## hwloc_get_next_obj_covering_cpuset_by_depth()

static hwloc_obj_t hwloc_get_next_obj_covering_cpuset_by_depth | ( | hwloc_topology_t | topology,
|  | hwloc_const_cpuset_t | set,
|  | int | depth,
|  | hwloc_obj_t | prev
| ) |  |

inlinestatic

Iterate through same-depth objects covering at least CPU set `set`.

If object `prev` is `NULL`, return the first object at depth `depth` covering at least part of CPU set `set`. The next invokation should pass the previous return value in `prev` so as to obtain the next object covering at least another part of `set`.

Note
  This function cannot work if objects at the given depth do not have CPU sets (I/O or Misc objects).

## hwloc_get_next_obj_covering_cpuset_by_type()

static hwloc_obj_t hwloc_get_next_obj_covering_cpuset_by_type | ( | hwloc_topology_t | topology,
|  | hwloc_const_cpuset_t | set,
|  | hwloc_obj_type_t | type,
|  | hwloc_obj_t | prev
| ) |  |

inlinestatic

Iterate through same-type objects covering at least CPU set `set`.

If object `prev` is `NULL`, return the first object of type `type` covering at least part of CPU set `set`. The next invokation should pass the previous return value in `prev` so as to obtain the next object of type `type` covering at least another part of `set`.

If there are no or multiple depths for type `type`, `NULL` is returned. The caller may fallback to hwloc_get_next_obj_covering_cpuset_by_depth() for each depth.

Note
  This function cannot work if objects of the given type do not have CPU sets (I/O or Misc objects).

## hwloc_get_obj_covering_cpuset()

static hwloc_obj_t hwloc_get_obj_covering_cpuset | ( | hwloc_topology_t | topology,
|  | hwloc_const_cpuset_t | set
| ) |  |

inlinestatic

Get the lowest object covering at least CPU set `set`.

Returns
  `NULL` if no object matches or if `set` is empty.
