XDIFF_STRING_RABDIFF(3) 						 1						   XDIFF_STRING_RABDIFF(3)

xdiff_string_rabdiff - Make binary diff of two strings using the Rabin's polynomial fingerprinting algorithm

SYNOPSIS

       string xdiff_string_bdiff (string  $old_data, string  $new_data)

DESCRIPTION

	Makes  a  binary  diff	of two strings and returns the result. The difference between this function and xdiff_string_bdiff(3) is different
       algorithm used which should result in faster execution and smaller diff produced. This function works  with  both  text	and  binary  data.
       Resulting patch can be later applied using xdiff_string_bpatch(3)/xdiff_file_bpatch(3).

	For more details about differences between algorithm used please check libxdiff website.

PARAMETERS

	      o $old_data
		- First string with binary data. It acts as "old" data.

	      o $new_data
		- Second string with binary data. It acts as "new" data.

RETURN VALUES

	Returns string with binary diff containing differences between "old" and "new" data or FALSE if an internal error occurred.
