## Detailed Description

## Function Documentation

## ◆ hwloc_obj_add_info()

int hwloc_obj_add_info | ( | hwloc_obj_t | obj,
|  | const char * | name,
|  | const char * | value
| ) |  |

Add the given info name and value pair to the given object.

The info is appended to the existing info array even if another key with the same name already exists.

The input strings are copied before being added in the object infos.

Returns
  `0` on success, `-1` on error.

Note
  This function may be used to enforce object colors in the lstopo graphical output by using "lstopoStyle" as a name and "Background=#rrggbb" as a value. See CUSTOM COLORS in the lstopo(1) manpage for details.
  If `value` contains some non-printable characters, they will be dropped when exporting to XML, see hwloc_topology_export_xml() in hwloc/export.h.

## ◆ hwloc_obj_get_info_by_name()

static const char * hwloc_obj_get_info_by_name | ( | hwloc_obj_t | obj,
|  | const char * | name
| ) |  |
| inline static

Search the given key name in object infos and return the corresponding value.

If multiple keys match the given name, only the first one is returned.

Returns
  A pointer to the value string if it exists.
  `NULL` if no such key exists.

Note
  The string should not be freed by the caller, it belongs to the hwloc library.
