| 225 | * @brief Generic getnext function for ::lys_getnext() and ::lys_getnext_ext(). |
| 226 | * |
| 227 | * Gets next schema tree (sibling) node element that can be instantiated in a data tree. Returned node can |
| 228 | * be from an augment. If the @p ext is provided, the function is locked inside the schema tree defined in the |
| 229 | * extension instance. |
| 230 | * |
| 231 | * ::lys_getnext_() is supposed to be called sequentially. In the first call, the \p last parameter is usually NULL |
| 232 | * and function starts returning i) the first \p parent's child or ii) the first top level element specified in the |
| 233 | * given extension (if provided) or iii) the first top level element of the \p module. |
| 234 | * Consequent calls suppose to provide the previously returned node as the \p last parameter and still the same |
| 235 | * \p parent and \p module parameters. |
| 236 | * |
| 237 | * Without options, the function is used to traverse only the schema nodes that can be paired with corresponding |
| 238 | * data nodes in a data tree. By setting some \p options the behavior can be modified to the extent that |
| 239 | * all the schema nodes are iteratively returned. |
| 240 | * |
| 241 | * @param[in] last Previously returned schema tree node, or NULL in case of the first call. |
| 242 | * @param[in] parent Parent of the subtree where the function starts processing. |
| 243 | * @param[in] module In case of iterating on top level elements, the \p parent is NULL and |
| 244 | * module must be specified. |
| 245 | * @param[in] ext The extension instance to provide a separate schema tree. To consider the top level elements in the tree, |
