* fake library for ssh
*
* This file includes getnameinfo().
* These funtions are defined in rfc2133.
*
* But these functions are not implemented correctly. The minimum subset
* is implemented for ssh use only. For exapmle, this routine assumes
* that ai_family is AF_INET. Don't use it for another purpose.
*
* In the case not using 'configure --enable-ipv6', this getnameinfo.c
* will be used if you have broken getnameinfo or no getnameinfo.
