PROLOG

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult 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_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.
