+ *          is described by \p memtype.
+ *
+ *          This routine combines calling H5Dset_extent(),
+ *          H5Sselect_hyperslab(), and H5Dwrite() into a single routine
+ *          that simplifies application development for the common case
+ *          of appending elements to an existing dataset.
+ *
+ *          For a multi-dimensional dataset, appending to one dimension
+ *          will write a contiguous hyperslab over the other dimensions.
+ *          For example, if a 3-D dataset has dimension sizes (3, 5, 8),
+ *          extending the 0th dimension (currently of size 3) by 3 will
+ *          append 3*5*8 = 120 elements (which must be pointed to by the
+ *          \p buffer parameter) to the dataset, making its final
+ *          dimension sizes (6, 5, 8).
+ *
+ *          If a dataset has more than one unlimited dimension, any of
+ *          those dimensions may be appended to, although only along

+ * \deprecated For compatibility, this API call has been left as a stub which
+ *             simply calls H5Dwrite_chunk(). New code should use H5Dwrite_chunk().
+ *
+ * \details The H5DOwrite_chunk() writes a raw data chunk as specified by its
+ *          logical \p offset in a chunked dataset \p dset_id from the application
+ *          memory buffer \p buf to the dataset in the file. Typically, the data
+ *          in \p buf is preprocessed in memory by a custom transformation, such as
+ *          compression. The chunk will bypass the library’s internal data
+ *          transfer pipeline, including filters, and will be written directly to the file.
+ *
+ *          \p dxpl_id is a data transfer property list identifier.
+ *
+ *          \p filters is a mask providing a record of which filters are used
+ *          with the chunk. The default value of the mask is zero (\c 0),
+ *          indicating that all enabled filters are applied. A filter is skipped
+ *          if the bit corresponding to the filter’s position in the pipeline
+ *          (<tt>0 ≤ position < 32</tt>) is turned on. This mask is saved
+ *          with the chunk in the file.
+ *
+ *          \p offset is an array specifying the logical position of the first
+ *          element of the chunk in the dataset’s dataspace. The length of the
+ *          offset array must equal the number of dimensions, or rank, of the
+ *          dataspace. The values in \p offset must not exceed the dimension limits
+ *          and must specify a point that falls on a dataset chunk boundary.
+ *
+ *          \p data_size is the size in bytes of the chunk, representing the number of
+ *          bytes to be read from the buffer \p buf. If the data chunk has been
+ *          precompressed, \p data_size should be the size of the compressed data.
+ *
+ *          \p buf is the memory buffer containing data to be written to the chunk in the file.
+ *
+ * \attention   Exercise caution when using H5DOread_chunk() and H5DOwrite_chunk(),
+ *              as they read and write data chunks directly in a file.
+ *              H5DOwrite_chunk() bypasses hyperslab selection, the conversion of data
+ *              from one datatype to another, and the filter pipeline to write the chunk.
+ *              Developers should have experience with these processes before
+ *              using this function. Please see
+ *              <a href="https://portal.hdfgroup.org/display/HDF5/Using+the+Direct+Chunk+Write+Function">

+ *
+ * \note    H5DOread_chunk() and H5DOwrite_chunk() are not
+ *          supported under parallel and do not support variable length types.

+ *          \p cur_dims indicates the dimension sizes of the data to be
+ *          selected from the dataset. Note that \p cur_dims must have
+ *          at least one dimension whose size is greater than the
+ *          corresponding dimension in \p prev_dims. Users can

+ *
+ *          If the parameter \p fields is NULL, this routine returns

+ *          is not NULL and the dataset has a compound datatype, \p fields
+ *          is a string containing a comma-separated list of fields.
+ *          Each name in \p fields specifies a field in the compound
+ *          datatype, and this routine returns data of the selected fields
+ *          for the dataset's selected elements. Note that ’,’ is the
+ *          separator for the fields of a compound datatype while
+ *          ’.’ is the separator for a nested field. Use backslash to
+ *          escape characters in field names that conflict with these

+ * \param[in] check_object_valid    If TRUE, determine whether the final
+ *                                  component of \p path resolves to
+ *                                  an object; if FALSE, do not check.
+ *
+ * \return  Upon success:
+ * \return  If \p check_object_valid is set to \c FALSE:
+ * \return  Returns \c TRUE if the path is valid;
+ *          otherwise returns \c FALSE.
+ * \return  If \p check_object_valid is set to \c TRUE:
+ * \return  Returns \c TRUE if the path is valid and
+ *          resolves to an HDF5 object;
+ *          otherwise returns \c FALSE.
+ *
+ * \return  Upon error, returns a negative value.
+ *
+ * \details H5LTpath_valid() checks the validity of \p path relative
+ *          to the identifier of an object, \p loc_id. Optionally,
+ *          \p check_object_valid can be set to determine whether the
+ *          final component of \p path resolves to an HDF5 object;
+ *          if not, the final component is a dangling link.
+ *
+ *          The meaning of the function’s return value depends on the
+ *          value of \p check_object_valid:
+ *
+ *          If \p check_object_valid is set to \c FALSE, H5LTpath_valid()
+ *          will check all links in \p path to verify that they exist.
+ *          If all the links in \p path exist, the function will
+ *          return \c TRUE; otherwise the function will return \c FALSE.
+ *
+ *          If \p check_object_valid is set to \c TRUE,
+ *          H5LTpath_valid() will first check the links in \p path,
+ *          as described above. If all the links exist,
+ *          \p check_object_valid will then determine whether the final
+ *          component of \p path resolves to an actual HDF5 object.
+ *          H5LTpath_valid() will return \c TRUE if all the links in
+ *          \p path exist and the final component resolves to an
+ *          actual object; otherwise, it will return \c FALSE.
+ *
+ *          \p path can be any one of the following:
+ *
+ *          - An absolute path, which starts with a slash (\c /)
+ *            indicating the file’s root group, followed by the members
+ *          - A relative path with respect to \p loc_id
+ *          - A dot (\c .), if \p loc_id is the object identifier for
+ *            the object itself
+ *          .
+ *
+ *          If \p path is an absolute path, then \p loc_id can be an
+ *          identifier for any object in the file as it is used only to
+ *          identify the file. If \p path is a relative path, then
+ *          \p loc_id must be a file or a group identifier.
+ *
+ * \note
+ * <b>Note on Behavior Change:</b>
+ * The behavior of  H5LTpath_valid() was changed in the 1.10.0 release
+ * in the case where the root group, “/”, is the value of path.
+ * This change is described below:
+ *     - Let \p loc_id denote a valid HDF5 file identifier, and let
+ *       \p check_object_valid be set to true or false.
+ *       A call to  H5LTpath_valid() with arguments \p loc_id, “/”,
+ *       and \p check_object_valid returns a positive value;
+ *       in other words, H5LTpath_valid(loc_id, "/", check_object_valid)
+ *       returns a positive value.
+ *       In HDF5 version 1.8.16, this function returns 0.
+ *     - Let ‘root’ denote a valid HDF5 group identifier that refers
+ *       to the root group of an HDF5 file, and let \p check_object_valid
+ *       be set to true or false.
+ *       A call to H5LTpath_valid() with arguments ‘root’, “/”, and
+ *       \p check_object_valid returns a positive value;
+ *       in other words, H5LTpath_valid(root, "/", check_object_valid)
+ *       returns a positive value.
+ *       In HDF5 version 1.8.16, this function returns 0.
+ *

+ * <em>Creating and manipulating HDF5 datasets to support append-
+ * and read-only operations on table data (H5PT)</em>
+ *
+ * The HDF5 Packet Table API is designed to allow records to be
+ * appended to and read from a table. Packet Table datasets are
+ * chunked, allowing them to grow as needed.
+ *
+ * The Packet Table API, with the H5PT prefix, is not to be confused with
+ * the H5TB Table API (H5TB prefix). The H5TB APIs are stateless
+ * (H5TB Tables do not need to be opened or closed) but H5PT Packet Tables
+ * require less performance overhead. Also, H5TB Tables support insertions
+ * and deletions, while H5PT Packet Tables support only append operations.
+ * H5TB functions should not be called on tables created with the
+ * H5PT API, or vice versa.
+ *
+ * Packet Tables are datasets in an HDF5 file, so while their contents
+ * should not be changed outside of the H5PT API calls, the datatypes of
+ * Packet Tables can be queried using \ref H5Dget_type.
+ * Packet Tables can also be given attributes using the normal HDF5 APIs.
+ *
+ * \note \Bold{Programming hints:}
+ * \note The following line includes the HDF5 Packet Table package, H5PT,
+ *       in C applications:
+ *       \code #include "hdf5_hl.h" \endcode
+ *       Without this include, an application will not have access to
+ *       these functions.

+ * The HDF5 Table API defines a standard storage for HDF5 datasets
+ * that are intended to be interpreted as tables. A table is defined
+ * as a collection of records whose values are stored in fixed-length
+ * fields. All records have the same structure, and all values in
+ * each field have the same data type.
+ *
+ * \note \Bold{Programming hints:}
+ * \note To use any of these functions or subroutines,
+ *       you must first include the relevant include file (C) or
+ *       module (Fortran) in your application.
+ * \note The following line includes the HDF5 Table package, H5TB,
+ *       in C applications:
+ *       \code #include "hdf5_hl.h" \endcode
+ * \note To include the H5TB module in Fortran applications specify:
+ *       \code use h5tb \endcode
+ *       Fortran applications must also include \ref H5open before
+ *       any HDF5 calls to initialize global variables and \ref H5close
+ *       after all HDF5 calls to close the Fortran interface.
