1/*
2 * fake library for ssh
3 *
4 * This file includes getnameinfo().
5 * These funtions are defined in rfc2133.
6 *
7 * But these functions are not implemented correctly. The minimum subset
8 * is implemented for ssh use only. For exapmle, this routine assumes
9 * that ai_family is AF_INET. Don't use it for another purpose.
