NAME
       SPI_scroll_cursor_move - move a cursor

SYNOPSIS
       void SPI_scroll_cursor_move(Portal portal, FetchDirection direction,
				   long count)

DESCRIPTION
       SPI_scroll_cursor_move skips over some number of rows in a cursor. This
       is equivalent to the SQL command MOVE.

ARGUMENTS
       Portal portal
	   portal containing the cursor

       FetchDirection direction
	   one of FETCH_FORWARD, FETCH_BACKWARD, FETCH_ABSOLUTE or
	   FETCH_RELATIVE

       long count
	   number of rows to move for FETCH_FORWARD or FETCH_BACKWARD;
	   absolute row number to move to for FETCH_ABSOLUTE; or relative row
	   number to move to for FETCH_RELATIVE

RETURN VALUE
       SPI_processed is set as in SPI_execute if successful.  SPI_tuptable is
       set to NULL, since no rows are returned by this function.

NOTES
       See the SQL FETCH(7) command for details of the interpretation of the
       direction and count parameters.

       Direction values other than FETCH_FORWARD may fail if the cursor's plan
       was not created with the CURSOR_OPT_SCROLL option.
