PROLOG         top

       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         top

       gai_strerror — address and name information error description

SYNOPSIS         top

       #include <netdb.h>
       const char *gai_strerror(int ecode);

DESCRIPTION         top

       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         top

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