Yeah, but it's disgusting, at least I can't see a sane way of declaring
the cmessage type without using it, here's what you can do:

1) leave it in sys/socket.h

2) put the cmessage struct in each file

3) declare consumers of cmessage as so:
	struct {
		struct cmsghdr cmsg;
		struct cmsgcred cmcred;
	} cm;

4) or do this:
	char cm[sizeof(struct cmsghdr) + sizeof(struct cmsgcred)];

I'll wait for you to decide or point to something that I can crib
from.

thanks,

Instead of asking why a piece of software is using "1970s technology,"
start asking why software is ignoring 30 years of accumulated wisdom.
