H5S_GET_SELECT_ELEM_POINTLIST returns the list of element points in the current dataspace selection
space_id. Starting with the
startpoint in the list of points,
numpoints points are put into the user's buffer. If the user's buffer fills up before
numpoints points are inserted, the buffer will contain only as many points as fit.
The element point coordinates have the same dimensionality (rank) as the dataspace they are located within. The list of element points is formatted as follows:
<coordinate>, followed by
the next coordinate,
until all of the selected element points have been listed.
The points are returned in the order they will be iterated through when the selection is read/written from/to disk.
