NAME
       gai_strerror - address and name information error description


SYNOPSIS
       #include <netdb.h>

       const char *gai_strerror(int ecode);


DESCRIPTION
       The  gai_strerror()  function  shall return a text string describing an error value for the getaddrinfo()
       and getnameinfo() functions listed in the <netdb.h> header.

       When the ecode argument is one of the following values listed in the <netdb.h> header:

              [EAI_AGAIN]
              [EAI_BADFLAGS]
              [EAI_FAIL]
              [EAI_FAMILY]
              [EAI_MEMORY]
              [EAI_NONAME]

              [EAI_SERVICE]
              [EAI_SOCKTYPE]
              [EAI_SYSTEM]

       the function return value shall point to a string describing the error.  If the argument is  not  one  of
       those values, the function shall return a pointer to a string whose contents indicate an unknown error.
