Quoting Bou Aek <[email protected]> from ml.gnutella.dev-forum:
:I am trying to use this method to read the content of QueryHit message, 
:But it never gives me the correct result. 

Of course, your parsing is incorrect.  The 0.4 protocol specified that each
filename is ended by two NUL characters.  It was extended to allow further
data to optionally be put between the two NUL, so in effect the first NUL
terminates the filename and the second NUL terminates the extension block.

To parse the extension block, you'll have to read the HUGE document and
the GGEP document.  Modern servent use GGEP now for extensions, but there
may still be some legacy HUGE data in extensions sent by "dead" servents
(i.e. unmaintained old code still in use somewhere).

For now you can just ignore the extension until you get something that works.
