SYNOPSIS

#include <ne_socket.h>

typedef enum {
ne_iaddr_ipv4 = 0,
ne_iaddr_ipv6 } ne_iaddr_type;

ne_inet_addr *ne_iaddr_make (ne_iaddr_type type, const unsigned char *raw);
int ne_iaddr_cmp (const ne_inet_addr *ia1, const ne_inet_addr *ia2);
char *ne_iaddr_print (const ne_inet_addr *ia, char *buffer, size_t bufsiz);
ne_iaddr_type ne_iaddr_typeof (const ne_inet_addr *ia);
void ne_iaddr_free (const ne_inet_addr *ia);

DESCRIPTION

ne_iaddr_make creates an ne_inet_addr object from a raw binary network address; for instance the four bytes 0x7f 0x00 0x00 0x01 represent the IPv4 address 127.0.0.1. The object returned is suitable for passing to ne_sock_connect. A binary IPv4 address contains four bytes; a binary IPv6 address contains sixteen bytes; addresses passed must be in network byte order.

ne_iaddr_cmp can be used to compare two network addresses; returning zero only if they are identical. The addresses need not be of the same address type; if the addresses are not of the same type, the return value is guaranteed to be non-zero.

ne_iaddr_print can be used to print the human-readable string representation of a network address into a buffer, for instance the string "127.0.0.1".

ne_iaddr_typeof returns the type of the given network address.

ne_iaddr_free releases the memory associated with a network address object.

RETURN VALUE

ne_iaddr_make returns NULL if the address type passed is not supported (for instance on a platform which does not support IPv6).

ne_iaddr_print returns the buffer pointer, and never NULL.

EXAMPLES

The following example connects a socket to port 80 at the address 127.0.0.1.

unsigned char addr[] = "\0x7f\0x00\0x00\0x01";
ne_inet_addr *ia;

ia = ne_iaddr_make(ne_iaddr_ipv4, addr); if (ia != NULL) { ne_socket *sock = ne_sock_connect(ia, 80); ne_iaddr_free(ia); /* ... */ } else { /* ... */ }
