Scrollable Cursors
The application requests a scrollable cursor by setting the IIAPI_QF_SCROLL flag when opening the cursor using IIapi_query() with query type IIAPI_QT_OPEN. A scrollable cursor can be positioned prior to calling IIapi_getColumns() using either IIapi_scroll() or IIapi_position(). IIapi_getColumns() then returns rows starting with the row specified by IIapi_scroll() or IIapi_position(). If IIapi_getColumns() is not preceded by an explicit scroll/position request, the rows following the current cursor position are returned.
