 * Audience:    Public
 * Chapter:     H5Tools Library
 * Purpose:     Prints NELMTS data elements to output STREAM.
 * Description:
 *      Prints some (NELMTS) data elements to output STREAM. The elements are
 *      stored in _MEM as type TYPE and are printed according to the format
 *      described in INFO. The CTX struct contains context information shared
 *      between calls to this function. The FLAGS is a bit field that
 *      indicates whether the data supplied in this call falls at the
 *      beginning or end of the total data to be printed (START_OF_DATA and
 *      END_OF_DATA).
 * Return: Success:    SUCCEED
 *         Failure:    FAIL
 * Programmer:
 *      Robb Matzke, Monday, April 26, 1999
 * Modifications:
 *  Robb Matzke, 1999-06-04
 * The `container' argument is the optional dataset for reference types.
 *
 *  Robb Matzke, 1999-09-29
 * Understands the `per_line' property which indicates that every Nth
 * element should begin a new line.
 *
 *      Robb Matzke, LLNL, 2003-06-05
 *      Do not dereference the memory for a variable-length string here.
 *      Deref in h5tools_str_sprint() instead so recursive types are
 *      handled correctly.
 *
 *      Pedro Vicente Nunes, The HDF Group, 2005-10-19
 *        pass to the prefix in h5tools_simple_prefix the total position
 *        instead of the current stripmine position i; this is necessary
 *        to print the array indices

 * Audience:    Public

 * Purpose: Print some values from a dataset with a simple data space.
 * Description:
 *      This is a special case of h5tools_dump_dset(). This function only
 *      intended for dumping datasets -- it does strip mining and some other
 *      things which are unnecessary for smaller objects such as attributes
 *      (to print small objects like attributes simply read the attribute and
 *      call h5tools_dump_simple_mem()).
 * Return:
 *      On success, the function returns SUCCEED. Otherwise, the function
 *      returns FAIL.
