Yes, without various checks it expands to (struct cmsghdr *)((char *)(cmsg) + \ _ALIGN(((struct cmsghdr *)(cmsg))->cmsg_len)) Although there is no alignment problem (assuming cmsg is properly aligned and _ALIGN is correct), this violates -Wcast-align. Therefore I think an intermediate cast to void * would be appropriate here. -- Jilles Tjoelker _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[email protected]"
