A while back I did some testing of this point. These were the results I noted: FreeBSD 4.8 O_NONBLOCK and O_ASYNC are inherited FD_CLOEXEC is not inherited Solaris 8 O_NONBLOCK and O_ASYNC are inherited FD_CLOEXEC is not inherited Tru64 5.1 (sep 03, testdrive) No F_SETFL flags are inherited FD_CLOEXEC is not inherited HP-UX 11 No F_SETFL flags are inherited FD_CLOEXEC is not inherited -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
