H5S_GET_SELECT_ELEM_POINTLIST
Gets the list of element points currently selected
Procedure:
H5S_GET_SELECT_ELEM_POINTLIST ( space_id, startpoint, numpoints, buf )
Signature:
herr_t H5Sget_select_elem_pointlist(hid_t space_id,
hsize_t startpoint,
hsize_t numpoints,
hsize_t *buf
)
Fortran90 Interface: h5sget_select_elem_pointlist_f
SUBROUTINE h5sget_select_elem_pointlist_f(space_id, startpoint, num_points,
buf, hdferr)
IMPLICIT NONE
INTEGER(HID_T), INTENT(IN) :: space_id ! Dataspace identifier
INTEGER(HSIZE_T), INTENT(IN) :: startpoint ! Element point to start with
INTEGER, INTENT(OUT) :: num_points ! Number of points to get in
! the current element selection
INTEGER(HSIZE_T), DIMENSION(*), INTENT(OUT) :: buf
! List of points selected
INTEGER, INTENT(OUT) :: hdferr ! Error code
END SUBROUTINE h5sget_select_elem_pointlist_f
Parameters:
hid_t space_id | IN: Dataspace identifier of selection to query |
hsize_t startpoint | IN: Element point to start with |
hsize_t numpoints | IN: Number of element points to get |
hsize_t *buf | OUT: List of element points selected |
Description:
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,
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.
