FreeBSD[1] chose signatures of: int bindat(int fd, int s, const struct sockaddr *addr, socklen_t addrlen); int connectat(int fd, int s, const struct sockaddr *name, socklen_t namelen); An alternate implementation could instead augment `sockaddr_un`. Also, if we're going to add a new bind and connect() syscalls, we should also add a flags argument.
