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.
