+ Non-negative on success / Negative on failure
+ DESCRIPTION
+ Retrieve a list of offset / length pairs (a list of "sequences") matching
+ the selected elements for an iterator, according to the iteration order for
+ the iterator. The lengths returned are in _bytes_, not elements.
+
+ Note that the iteration order for "all" and "hyperslab" selections is
+ row-major (i.e. "C-ordered"), but the iteration order for "point"
+ selections is "in order selected", unless the H5S_SEL_ITER_GET_SEQ_LIST_SORTED
+ flag is passed to H5Sset_iter_create for a point selection.
+
+ MAXSEQ and MAXBYTES specify the most sequences or bytes possible to
+ place into the OFF and LEN arrays. *NSEQ and *NBYTES return the actual
+ number of sequences and bytes put into the arrays.
+
+ Each call to H5Ssel_iter_get_seq_list() will retrieve the next set
+ of sequences for the selection being iterated over.
+
+ The total number of bytes possible to retrieve from a selection iterator
+ is the 'elmt_size' passed to H5Ssel_iter_create multiplied by the number
+ of elements selected in the dataspace the iterator was created from
+ (which can be retrieved with H5Sget_select_npoints). When there are no
+ further sequences of elements to retrieve, calls to this routine will
+ set *NSEQ and *NBYTES to zero.
