Since it's quite useless so far and since I am not sure I quite understand what you mean by useless. is cygwin implementation somehow deficient? > applications using this structure should accomodate the old > implementation anyway, I don't see a good reason to change this right > now. the only reason applications have to accommodate the old implementation is that some unixes still stick with it. if you switch to the posix msghdr, I, for one, would not have to accomodate the old implementation. -- Sam Steingold (http://www.podval.org/~sds) running w2k Two wrongs don't make a right, but three rights make a left. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
