NAME

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

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[] = "x7fx00x00x01";
	   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 {
	       /* ... */
	   }
