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_NONAME]
       [EAI_BADFLAGS]	[EAI_OVERFLOW]
       [EAI_FAIL]	[EAI_SERVICE]
       [EAI_FAMILY]	[EAI_SOCKTYPE]
       [EAI_MEMORY]	[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.

RETURN VALUE
       Upon successful completion, gai_strerror() shall return a pointer to an implementation-defined string.
