## Functions

hwloc_obj_t | hwloc_get_obj_by_depth (hwloc_topology_t topology, unsigned depth, unsigned idx)
static inline hwloc_obj_t | hwloc_get_obj_by_type (hwloc_topology_t topology, hwloc_obj_type_t type, unsigned idx)

## Detailed Description

Be sure to see the figure in Terms and Definitions 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

hwloc_obj_t hwloc_get_obj_by_depth | ( | hwloc_topology_t | topology,
|  | unsigned | depth,
|  | unsigned | idx
| ) |  |

Returns the topology object at logical index `idx` from depth `depth`.

static inline hwloc_obj_t hwloc_get_obj_by_type | ( | hwloc_topology_t | topology,
|  | hwloc_obj_type_t | type,
|  | unsigned | idx
| ) |  |

static

Returns the topology object at logical index `idx` with type `type`.

If no object for that type exists, `NULL` is returned. If there are several levels with objects of that type, `NULL` is returned and ther caller may fallback to hwloc_get_obj_by_depth().
