   (PHP 3 CVS only)
   sesam_seek_row --  Set scrollable cursor mode for subsequent fetches

Description

   bool sesam_seek_row ( string result_id, int whence [, int offset])

   result_id is a valid result id (select type queries only, and only if
   a "scrollable" cursor was requested when calling sesam_query()).

   whence sets the global default value for the scrolling type, it
   specifies the scroll type to use in subsequent fetch operations on
   "scrollable" cursors, which can be set to the following predefined
   constants:

   Table 1. Valid values for "whence" parameter
   Value Constant Meaning
   0 SESAM_SEEK_NEXT read sequentially
   1 SESAM_SEEK_PRIOR read sequentially backwards
   2 SESAM_SEEK_FIRST fetch first row (after fetch, the default is set to
   SESAM_SEEK_NEXT)
   3 SESAM_SEEK_LAST fetch last row (after fetch, the default is set to
   SESAM_SEEK_PRIOR)
   4 SESAM_SEEK_ABSOLUTE fetch absolute row number given as offset
   (Zero-based. After fetch, the default is set to SESAM_SEEK_ABSOLUTE,
   and the offset value is auto-incremented)
   5 SESAM_SEEK_RELATIVE fetch relative to current scroll position, where
   offset can be a positive or negative offset value (this also sets the
   default "offset" value for subsequent fetches).

   offset is an optional parameter which is only evaluated (and required)
   if whence is either SESAM_SEEK_RELATIVE or SESAM_SEEK_ABSOLUTE.
