NAME

6       ne_iaddr_make, ne_iaddr_cmp, ne_iaddr_print, ne_iaddr_typeof,
7       ne_iaddr_free - functions to manipulate and compare network addresses

SYNOPSIS

10       #include <ne_socket.h>
11
12       typedef enum {
13           ne_iaddr_ipv4 = 0,
14           ne_iaddr_ipv6
15       } ne_iaddr_type;
16
17       ne_inet_addr *ne_iaddr_make(ne_iaddr_type type,
18                                   const unsigned char *raw);
19
20       int ne_iaddr_cmp(const ne_inet_addr *ia1, const ne_inet_addr *ia2);
21
22       char *ne_iaddr_print(const ne_inet_addr *ia, char *buffer,
23                            size_t bufsiz);
24
25       ne_iaddr_type ne_iaddr_typeof(const ne_inet_addr *ia);
26
27       void ne_iaddr_free(const ne_inet_addr *ia);

DESCRIPTION

30       ne_iaddr_make creates an ne_inet_addr object from a raw binary network
31       address; for instance the four bytes 0x7f 0x00 0x00 0x01 represent the
32       IPv4 address 127.0.0.1. The object returned is suitable for passing to
33       ne_sock_connect. A binary IPv4 address contains four bytes; a binary
34       IPv6 address contains sixteen bytes; addresses passed must be in
35       network byte order.
36
37       ne_iaddr_cmp can be used to compare two network addresses; returning
38       zero only if they are identical. The addresses need not be of the same
39       address type; if the addresses are not of the same type, the return
40       value is guaranteed to be non-zero.
41
42       ne_iaddr_print can be used to print the human-readable string
43       representation of a network address into a buffer, for instance the
44       string "127.0.0.1".
45
46       ne_iaddr_typeof returns the type of the given network address.
47
48       ne_iaddr_free releases the memory associated with a network address
49       object.
50

RETURN VALUE

52       ne_iaddr_make returns NULL if the address type passed is not supported
53       (for instance on a platform which does not support IPv6).
54
55       ne_iaddr_print returns the buffer pointer, and never NULL.
56

EXAMPLES

58       The following example connects a socket to port 80 at the address
59       127.0.0.1.
60
61           unsigned char addr[] = "\0x7f\0x00\0x00\0x01";
62           ne_inet_addr *ia;
63
64           ia = ne_iaddr_make(ne_iaddr_ipv4, addr);
65           if (ia != NULL) {
66               ne_socket *sock = ne_sock_connect(ia, 80);
67               ne_iaddr_free(ia);
68               /* ... */
69           } else {
70               /* ... */
71           }
