I added section about using (u)char* arguments after I fixed uchar*
marshalling in qtruby. I have no time to find out if it also apply for
methods returning those pointers. here is link to this section i kde
wiki:

http://techbase.kde.org/Development/Languages/Ruby#C.2B.2B_.28const_.29.28unsigned_.29char.2A_argument_types

Please answer if this apply to methods returning those pointers or
what is the diference and then I can update wiki.
