Pawel's suggestion makes more sense to be honest. If this should be added to sysconf(3) and is worthy of abstracting out into a more generalized concept, then it might be a good idea to get into POSIX. However, it would need to be hashed out because the current implementation is very FreeBSD centric of course :). _______________________________________________ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
