DESCRIPTION
     The gai_strerror() function returns an error message string corresponding
     to the error code returned by getaddrinfo(3) or getnameinfo(3).

     The following error codes and their meaning are defined in <netdb.h>:

           EAI_BADFLAGS      flags parameter had an invalid value
           EAI_BADHINTS      invalid value for hints
           EAI_FAIL          Non-recoverable failure in name resolution
           EAI_FAMILY        Address family was not recognized
           EAI_MEMORY        Memory allocation failure
           EAI_NONAME        Name does not resolve
           EAI_OVERFLOW      argument buffer overflow
           EAI_PROTOCOL      Resolved protocol is unknown
           EAI_SERVICE       Service was not recognized for socket type
           EAI_SOCKTYPE      Intended socket type was not recognized
           EAI_SYSTEM        System error returned in errno
