Parameters:
hid_t space_idIN: Dataspace identifier of selection to query.
hsize_t startpoint    IN: Element point to start with.
hsize_t numpointsIN: Number of element points to get.
hsize_t *bufOUT: List of element points selected.

Description:

H5Sget_select_elem_pointlist returns the list of element points in the current dataspace selection. Starting with the startpoint-th point 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,

     etc.

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.

Returns:

Returns a non-negative value if successful; otherwise returns a negative value.
