| 495 | * Specific @p data_type values have different parameter meaning as follows: |
| 496 | * - ::LYD_TYPE_RPC_NETCONF: |
| 497 | * - @p parent - must be NULL, the whole RPC is expected; |
| 498 | * - @p format - must be ::LYD_XML, NETCONF supports only this format; |
| 499 | * - @p tree - must be provided, all the NETCONF-specific XML envelopes will be returned here as |
| 500 | * a separate opaque data tree, even if the function fails, this may be returned; |
| 501 | * - @p op - must be provided, the RPC/action data tree itself will be returned here, pointing to the operation; |
| 502 | * |
| 503 | * - ::LYD_TYPE_NOTIF_NETCONF: |
| 504 | * - @p parent - must be NULL, the whole notification is expected; |

| 509 | * |
| 510 | * - ::LYD_TYPE_REPLY_NETCONF: |
| 511 | * - @p parent - must be set, pointing to the invoked RPC operation (RPC or action) node; |
| 512 | * - @p format - must be ::LYD_XML, NETCONF supports only this format; |
| 513 | * - @p tree - must be provided, all the NETCONF-specific XML envelopes will be returned here as |
| 514 | * a separate opaque data tree, even if the function fails, this may be returned; |
| 515 | * - @p op - must be NULL, the reply is appended to the RPC; |
| 516 | * Note that there are 3 kinds of NETCONF replies - ok, error, and data. Only data reply appends any nodes to the RPC. |
| 517 | * |
| 518 | * @param[in] ctx libyang context. |
| 519 | * @param[in] ext Extension instance providing the specific schema tree to match with the data being parsed. |
| 520 | * @param[in] parent Optional parent to connect the parsed nodes to. |
| 521 | * @param[in] in Input handle to read the input from. |
| 522 | * @param[in] format Expected format of the data in @p in. |
