And where every binary have to duplicate the same code? I also don't know how passing arguments to .so is different than passing them to external binary. At least here we can verify ABI and we can eventually verify other things (like which options are supported, etc.). The .so have to parse arguments, use build_iovec() and return. In my opinion it'll save a lot of code duplication. --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
