cubrid_lob2_seek64 - Move the cursor of a lob object.

SYNOPSIS

       bool cubrid_lob2_seek64 (resource  $lob_identifier, string  $offset, [int  $origin = CUBRID_CURSOR_CURRENT])

DESCRIPTION

	The  cubrid_lob2_seek64(3)  function  is used to move the cursor position of a lob object by the value set in the $offset argument, to the
       direction set in the $origin argument. If the $offset you want to move is larger than an integer data can be stored, you can use this func-
       tion.

	To set the $origin argument, you can use CUBRID_CURSOR_FIRST to set the cursor position moving forward $offset units from the first begin-
       ning. In this case, $offset must be a positive value.

	If you use CUBRID_CURSOR_CURRENT for $origin, you can move forward or backward. and $offset can be positive or negative.

	If you use CUBRID_CURSOR_LAST for $origin, you can move backward $offset units from the end of LOB object and $offset only  can  be  posi-
       tive.

       Note

	       If you use this function to move the cursor position of the lob object, you should pass $offset as a string.

PARAMETERS

	      o $lob_identifier
		-Lob identifier as a result of cubrid_lob2_new(3) or get from the result set.

	      o $offset
		-Number of units you want to move the cursor.

	      o $origin
		-This parameter can be the following values:CUBRID_CURSOR_FIRST: move forward from the first beginning.CUBRID_CURSOR_CURRENT: move
		forward or backward from the current position.CUBRID_CURSOR_LAST: move backward at the end of LOB object.

RETURN VALUES

       TRUE if the process is successful and FALSE for failure.
