NAME

12       gai_strerror — address and name information error description
13

SYNOPSIS

15       #include <netdb.h>
16
17       const char *gai_strerror(int ecode);
18

DESCRIPTION

20       The gai_strerror() function shall return a text  string  describing  an
21       error value for the getaddrinfo() and getnameinfo() functions listed in
22       the <netdb.h> header.
23
24       When the ecode argument is one of the following values  listed  in  the
25       <netdb.h> header:
26
27       [EAI_AGAIN]      [EAI_NONAME]
28       [EAI_BADFLAGS]   [EAI_OVERFLOW]
29       [EAI_FAIL]       [EAI_SERVICE]
30       [EAI_FAMILY]     [EAI_SOCKTYPE]
31       [EAI_MEMORY]     [EAI_SYSTEM]
32
33       the function return value shall point to a string describing the error.
34       If the argument is not one of those values, the function shall return a
35       pointer to a string whose contents indicate an unknown error.
36

RETURN VALUE

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