PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult the corresponding Linux manual page for details of Linux behavior), or the  interface  may  not  be  implemented  on
       Linux.

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_OVERFLOW]
              [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.

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