- * Function: H5VL__native_link_move
- *
- * Purpose: Renames an object within an HDF5 file and moves it to a new
- * group. The original name SRC is unlinked from the group graph
- * and then inserted with the new name DST (which can specify a
- * new path for the object) as an atomic operation. The names
- * are interpreted relative to SRC_LOC_ID and
- * DST_LOC_ID, which are either file IDs or group ID.
- *
- * Return: Non-negative on success/Negative on failure
- *
- * Programmer: Mohamad Chaarawi
