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
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
29              [EAI_AGAIN]
30              [EAI_BADFLAGS]
31              [EAI_FAIL]
32              [EAI_FAMILY]
33              [EAI_MEMORY]
34              [EAI_NONAME]
35              [EAI_OVERFLOW]
36              [EAI_SERVICE]
37              [EAI_SOCKTYPE]
38              [EAI_SYSTEM]
39
40       the function return value shall point to a string describing the error.
41       If the argument is not one of those values, the function shall return a
42       pointer to a string whose contents indicate an unknown error.
43

RETURN VALUE

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