RFC 2553 was obsoleted by RFC 3493, and it added IPV6_V6ONLY into Basic API. RFC 2292 (IPV6 Advanced API) defines IPV6_CHECKSUM, and IPV6_PKTINFO (latter of which is known above as IPV6_2292PKTINFO) RFC 3542 obsoletes RFC 2292, and defines IPV6_RECVPKTINFO, and modifies IPV6_PKTINFO. The IPV6_JOIN_ANYCAST and IPV6_LEAVE_ANYCAST are not defined in any RFC. Undocumented are also IPV6_JOIN_GROUP and IPV6_LEAVE_GROUP (RFC 2553 / 3493) It really looks like time for major overhaul of that (and related) man-pages is needed... > Cheers, > > Michael > -- > Michael Kerrisk > maintainer of Linux man pages Sections 2, 3, 4, 5, and 7 /Matti Aarnio
