RFC 2553 Emulation - Provides emulation for RFC 2553 getaddrinfo,
4
freeaddrinfo and getnameinfo
6
These functions are necessary to write portable protocol independent
7
networking. They transparently support IPv4, IPv6 and probably many
8
other protocols too. This implementation is needed when the host does
9
not support these standards. It implements a simple wrapper that
10
basically supports only IPv4.
12
Perfect emulation is not provided, but it is passable..

Originally written by Jason Gunthorpe <jgg@debian.org> and placed into
15
the Public Domain, do with it what you will.

23
* Revision 2.2 2012/01/07 13:52:23 green
24
* Removed C++ comments (bad style, I know)
26
* Revision 2.1 2012/01/03 17:25:32 green
27
* Implemented IPv6 support
28
* - replace (almost) all getXbyY function calls with getaddrinfo/getnameinfo (RFC2553) calls
29
* - Add compatibility layer for target systems not supporting RFC2553 calls in rfc2553.[ch]
30
* - Add support for multiple listen sockets -- one for IPv4 and one for IPv6 (use V6ONLY)
31
* - For WIN32 platform add configuration parameter IPV6 (mutually exclusive with BINKD9X)
32
* - On WIN32 platform use Winsock2 API if IPV6 support is requested
33
* - config: node IP address literal + port supported: [<ipv6 address>]:<port>
