Discussion
%SS2_GETNAMEINFO retrieves a host name using the host address in_addr6 as a search parameter. It supports both IPv4 and IPv6 formatted addresses.
The form of h_name depends on the system implementation (and on whether you pass NI_NOFQDN). For example, it may return a simple host name such as socrates or a fully-qualified domain name such as socrates.synergex.com. If you pass the NI_NOFQDN flag, it will return only the simple host name, even if the domain name is available.
If h_name cannot be determined, the numeric form of in_addr6 is returned, unless you have specified NI_NAMEREQD, in which case SS_ENULL will be returned.
If SS_ENULL is returned, the system error code can be returned by immediately calling %SYSERR.
