Neither the core nor Socket supports the socket functions sendmsg and recvmsg.

Perhaps they should, as without them it's not possible to get/send ancillary
data. Then again, this is sufficiently low level that it's likely to be hard
to pack/unpack it without platform specific knowledge of the C structures
involved.

I would suggest adding these to the POSIX module then.

AFAICT, everything currently in POSIX does correspond to something in
the IEEE 1003.1 standard. That's not true of sendmsg/recvmsg.

Maybe they snuck into the 2001 edition, of which I don't have a copy.
But, unless they have, I'd say POSIX was not the place for these two.
How about Socket?

It is at least found in the 2004 edition​:

Socket is documented to be "just a translation of the C socket.h
file". All it does currently is to set up constants and functions for
packing and unpackings the structs defined in this header file. IMHO,
a function to pack/unpack 'struct msghdr' make sense here but not the
interface to the syscalls themselves.

Thanks. I stand corrected.
