+/** \brief Return an object of a different type with same locality.
+ *
+ * If the source object \p src is a normal or memory type,
+ * this function returns an object of type \p type with same
+ * CPU and node sets, either below or above in the hierarchy.
+ *
+ * If the source object \p src is a PCI or an OS device within a PCI
+ * device, the function may either return that PCI device, or another
+ * OS device in the same PCI parent.
+ * This may for instance be useful for converting between OS devices
+ * such as "nvml0" or "rsmi1" used in distance structures into the
+ * the PCI device, or the CUDA or OpenCL OS device that correspond
+ * to the same physical card.
+ *
+ * If not \c NULL, parameter \p subtype only select objects whose
+ * subtype attribute exists and is \p subtype (case-insensitively),
+ * for instance "OpenCL" or "CUDA".
+ *
+ * If not \c NULL, parameter \p nameprefix only selects objects whose
+ * name attribute exists and starts with \p nameprefix (case-insensitively),
+ * for instance "rsmi" for matching "rsmi0".
+ *
+ * If multiple objects match, the first one is returned.
+ *
+ * This function will not walk the hierarchy across bridges since
+ * the PCI locality may become different.
+ * This function cannot also convert between normal/memory objects
+ * and I/O or Misc objects.
+ *
+ * \p flags must be \c 0 for now.
+ *
+ * \return An object with identical locality,
+ * matching \p subtype and \p nameprefix if any.
+ *
+ * \return \c NULL if no matching object could be found,
+ * or if the source object and target type are incompatible,
+ * for instance if converting between CPU and I/O objects.
