PLIST_ID is a property list - * which is used to pass user options and properties to the - * copy. The name, dst_name, must not already be taken by some - * other object in the destination group. - * - * H5Ocopy() will fail if the name of the destination object - * exists in the destination group. For example, - * H5Ocopy(fid_src, "/dset", fid_dst, "/dset", ...) - * will fail if "/dset" exists in the destination file - * - * OPTIONS THAT HAVE BEEN IMPLEMENTED. - * H5O_COPY_SHALLOW_HIERARCHY_FLAG - * If this flag is specified, only immediate members of - * the group are copied. Otherwise (default), it will - * recursively copy all objects below the group - * H5O_COPY_EXPAND_SOFT_LINK_FLAG - * If this flag is specified, it will copy the objects - * pointed by the soft links. Otherwise (default), it - * will copy the soft link as they are - * H5O_COPY_WITHOUT_ATTR_FLAG - * If this flag is specified, it will copy object without - * copying attributes. Otherwise (default), it will - * copy object along with all its attributes - * H5O_COPY_EXPAND_REFERENCE_FLAG - * 1) Copy object between two different files: - * When this flag is specified, it will copy objects that - * are pointed by the references and update the values of - * references in the destination file. Otherwise (default) - * the values of references in the destination will set to - * zero - * The current implementation does not handle references - * inside of other datatype structure. For example, if - * a member of compound datatype is reference, H5Ocopy() - * will copy that field as it is. It will not set the - * value to zero as default is used nor copy the object - * pointed by that field the flag is set - * 2) Copy object within the same file: - * This flag does not have any effect to the H5Ocopy(). - * Datasets or attributes of references are copied as they - * are, i.e. values of references of the destination object - * are the same as the values of the source object - * - * OPTIONS THAT MAY APPLY TO COPY IN THE FUTURE. - * H5O_COPY_EXPAND_EXT_LINK_FLAG - * If this flag is specified, it will expand the external links - * into new objects, Otherwise (default), it will keep external - * links as they are (default) - * - * PROPERTIES THAT MAY APPLY TO COPY IN FUTURE - * Change data layout such as chunk size - * Add filter such as data compression. - * Add an attribute to the copied object(s) that say the date/time - * for the copy or other information about the source file. - * - * The intermediate group creation property should be passed in - * using the lcpl instead of the ocpypl. - * - * Usage: H5Ocopy(src_loc_id, src_name, dst_loc_id, dst_name, ocpypl_id, lcpl_id) - * hid_t src_loc_id IN: Source file or group identifier. - * const char *src_name IN: Name of the source object to be copied - * hid_t dst_loc_id IN: Destination file or group identifier - * const char *dst_name IN: Name of the destination object - * hid_t ocpypl_id IN: Properties which apply to the copy - * hid_t lcpl_id IN: Properties which apply to the new hard link - * - * - * Return: SUCCEED/FAIL - * - *------------------------------------------------------------------------- - */ -herr_t -H5Ocopy(hid_t src_loc_id, const char *src_name, hid_t dst_loc_id, const char *dst_name, hid_t ocpypl_id, - hid_t lcpl_id) -{ - H5VL_object_t * vol_obj1 = NULL; /* object of src_id */ - H5VL_loc_params_t loc_params1; - H5VL_object_t * vol_obj2 = NULL; /* object of dst_id */ - H5VL_loc_params_t loc_params2; - herr_t ret_value = SUCCEED; /* Return value */ - - FUNC_ENTER_API(FAIL) - H5TRACE6("e", "i*si*sii", src_loc_id, src_name, dst_loc_id, dst_name, ocpypl_id, lcpl_id); - - /* Check arguments */ - if (!src_name || !*src_name) - HGOTO_ERROR(H5E_ARGS, H5E_BADVALUE, FAIL, "no source name specified") - if (!dst_name || !*dst_name) - HGOTO_ERROR(H5E_ARGS, H5E_BADVALUE, FAIL, "no destination name specified") - - /* Get correct property lists */ - if (H5P_DEFAULT == lcpl_id) - lcpl_id = H5P_LINK_CREATE_DEFAULT; - else if (TRUE != H5P_isa_class(lcpl_id, H5P_LINK_CREATE)) - HGOTO_ERROR(H5E_ARGS, H5E_BADTYPE, FAIL, "not link creation property list") - - /* Get object copy property list */ - if (H5P_DEFAULT == ocpypl_id) - ocpypl_id = H5P_OBJECT_COPY_DEFAULT; - else if (TRUE != H5P_isa_class(ocpypl_id, H5P_OBJECT_COPY)) - HGOTO_ERROR(H5E_ARGS, H5E_BADTYPE, FAIL, "not object copy property list") - - /* Set the LCPL for the API context */ - H5CX_set_lcpl(lcpl_id); - - /* Set up collective metadata if appropriate */ - if (H5CX_set_loc(src_loc_id) < 0) - HGOTO_ERROR(H5E_OHDR, H5E_CANTSET, FAIL, "can't set collective metadata read info") - - /* get the object */ - if (NULL == (vol_obj1 = (H5VL_object_t *)H5I_object(src_loc_id))) - HGOTO_ERROR(H5E_ARGS, H5E_BADTYPE, FAIL, "invalid location identifier") - loc_params1.type = H5VL_OBJECT_BY_SELF; - loc_params1.obj_type = H5I_get_type(src_loc_id); - - /* get the object */ - if (NULL == (vol_obj2 = (H5VL_object_t *)H5I_object(dst_loc_id))) - HGOTO_ERROR(H5E_ARGS, H5E_BADTYPE, FAIL, "invalid location identifier") - loc_params2.type = H5VL_OBJECT_BY_SELF; - loc_params2.obj_type = H5I_get_type(dst_loc_id); - - /* Copy the object */ - if (H5VL_object_copy(vol_obj1, &loc_params1, src_name, vol_obj2, &loc_params2, dst_name, ocpypl_id, - lcpl_id, H5P_DATASET_XFER_DEFAULT, H5_REQUEST_NULL) < 0) - HGOTO_ERROR(H5E_OHDR, H5E_CANTCOPY, FAIL, "unable to copy object") - -done: - FUNC_LEAVE_API(ret_value) -} /* end H5Ocopy() */ - -/*------------------------------------------------------------------------- - * Function: H5O_copy + * Function: H5O__copy * * Purpose: Private version of H5Ocopy * @@ -256,18 +123,18 @@ done: *------------------------------------------------------------------------- */ herr_t -H5O_copy(const H5G_loc_t *loc, const char *src_name, H5G_loc_t *dst_loc, const char *dst_name, - hid_t ocpypl_id, hid_t lcpl_id) +H5O__copy(const H5G_loc_t *loc, const char *src_name, H5G_loc_t *dst_loc, const char *dst_name, + hid_t ocpypl_id, hid_t lcpl_id) { H5G_loc_t src_loc; /* Source object group location */ H5G_name_t src_path; /* Opened source object hier. path */ H5O_loc_t src_oloc; /* Opened source object object location */ - htri_t dst_exists; /* Does destination name exist already?
