The return error EDQUOT is not documented in open(2), write(2),
symlink(2) etc..
Whether inodes or disk blocks are required for each function
is something I based on received wisdom and BSD documentation,
rather than tracing the code to the kernel. For symlink(2)
this certainly depends on the file system type.
This patch was previously sent to the linux-man mailing list
as an RFC in September 2010.

Back in 2006, some text came in via Debian patches that seems
crufty. Remove it.

Glibc 2.0.6 is now so ld that the discussion of details
of that version can be deemphasized placing just under
NOTES.

In IPv4,IP_MTU is only supported by getsockopt.
In IPv6, we can use IPV6_MTU to set socket's MTU,
but the return value of getsockopt() is the path MTU.

The example uses sendmmsg() to send out a string "onetwo"
on a first datagram, where both halves originate from
distinct buffers and a second datagram contains "three",
coming from a single buffer.
Tested with netcat listening:
root@ubuntu:~# nc -l -u -p 1234
onetwothree
And tcpdump peeking:
root@ubuntu:~# tcpdump -c 2 -s 0 -X -ni lo tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on lo, link-type EN10MB (Ethernet), capture size 65535 bytes
