+ * 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:
+ *      None
+ * 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
+ *        new field sm_pos in h5tools_context_t, the current stripmine element position
