But there are absolutely no alignement problems with single-part
messages.  Actually, there are even fewer alignment problems without
NLMSG_* in this case because you don't need to use malloc() to allocate
the buffer. You could also use a simple variable of structure type with
automatic or static storage duration if the netlink datagram contains
such a structure.

BTW, are there any other reasons for using NLMSG_* apart from
alignement issues?
