PARAMETERS

	      o $result

	      o $row_number
		-This is the desired row number of the new result pointer.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      cubrid_data_seek(3) example

	      <?php
	      $conn = cubrid_connect("127.0.0.1", 33000, "demodb");

	      $req = cubrid_execute($conn, "SELECT * FROM code");
	      cubrid_data_seek($req, 0);

	      $result = cubrid_fetch_row($req);
	      var_dump($result);

	      cubrid_data_seek($req, 2);
	      $result = cubrid_fetch_row($req);
	      var_dump($result);

	      cubrid_data_seek($req, 4);
	      $result = cubrid_fetch_row($req);
	      var_dump($result);

	      cubrid_close_request($req);
	      cubrid_disconnect($conn);
	      ?>

	      The above example will output:

	      array(2) {
		[0]=>
		string(1) "X"
		[1]=>
		string(5) "Mixed"
	      }
	      array(2) {
		[0]=>
		string(1) "M"
		[1]=>
		string(3) "Man"
	      }
	      array(2) {
		[0]=>
		string(1) "S"
		[1]=>
		string(6) "Silver"
	      }
