NAME

13       gai_strerror — address and name information error description
14

SYNOPSIS

16       #include <netdb.h>
17
18       const char *gai_strerror(int ecode);
19

DESCRIPTION

21       The gai_strerror() function shall return a text  string  describing  an
22       error value for the getaddrinfo() and getnameinfo() functions listed in
23       the <netdb.h> header.
24
25       When the ecode argument is one of the following values  listed  in  the
26       <netdb.h> header:
27
28       [EAI_AGAIN]      [EAI_NONAME]
29       [EAI_BADFLAGS]   [EAI_OVERFLOW]
30       [EAI_FAIL]       [EAI_SERVICE]
31       [EAI_FAMILY]     [EAI_SOCKTYPE]
32       [EAI_MEMORY]     [EAI_SYSTEM]
33
34       the function return value shall point to a string describing the error.
35       If the argument is not one of those values, the function shall return a
36       pointer to a string whose contents indicate an unknown error.
37

RETURN VALUE

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