Functions
static const char * hwloc_obj_get_info_by_name (hwloc_obj_t obj, const
char *name)
int hwloc_obj_add_info (hwloc_obj_t obj, const char *name, const char

Detailed Description
Function Documentation
int hwloc_obj_add_info (hwloc_obj_t obj, const char * name, const char *
value)
Add the given name and value pair to the given object info attributes.
The info pair is appended to the existing info array even if another
pair 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 adding 'lstopoStyle' as a name and
'Background=#rrggbb' as a value. See CUSTOM COLORS in the lstopo(1)
manpage for details.
If name or value contain some non-printable characters, they will
be dropped when exporting to XML, see hwloc_topology_export_xml()
in hwloc/export.h.
static const char * hwloc_obj_get_info_by_name (hwloc_obj_t obj, const char
* name) [inline], [static]
Search the given name in object infos and return the corresponding
value. If multiple info attributes match the given name, only the first
one is returned.
Returns
A pointer to the value string if it exists.
NULL if no such info attribute exists.
Note
The string should not be freed by the caller, it belongs to the
hwloc library.
int hwloc_obj_set_subtype (hwloc_topology_t topology, hwloc_obj_t obj,
const char * subtype)
Set (or replace) the subtype of an object. The given subtype is copied
internally, the caller is responsible for freeing the original subtype
if needed.
If another subtype already exists in object, it is replaced. The given
subtype may be NULL to remove the existing subtype.
Note
This function is mostly meant to initialize the subtype of user-
added objects such as groups with
hwloc_topology_alloc_group_object().
Returns
0 on success.
-1 with errno set to ENOMEM on failure to allocate memory.
