It's actually a compatibility feature. The "new" ancillary data feature is not compatible with the old 4.2BSD msg_accrights, which was used only for file descriptor passing. Plus, the 'msghdr' structure itself is a different size. For that reason, we can't turn it on by default, at least for "normal" applications that link against -lsocket. It could potentially break those applications. We could do it for applcations that link against libc alone, though. -- James Carlson, Solaris Networking <[EMAIL PROTECTED]> Sun Microsystems / 35 Network Drive 71.232W Vox +1 781 442 2084 MS UBUR02-212 / Burlington MA 01803-2757 42.496N Fax +1 781 442 1677 _______________________________________________ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
