NE_IADDR_MAKE(3)	      neon API reference	      NE_IADDR_MAKE(3)

NAME
       ne_iaddr_make, ne_iaddr_cmp, ne_iaddr_print, ne_iaddr_typeof,
       ne_iaddr_parse, ne_iaddr_raw, ne_iaddr_reverse, ne_iaddr_free -
       functions to manipulate 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);

       ne_inet_addr *ne_iaddr_parse(const char *address, ne_iaddr_type type);

       unsigned char *ne_iaddr_raw(const ne_inet_addr *ia,
				   unsigned char *buffer);

       int ne_iaddr_reverse(const ne_inet_addr *ia, char *buffer,
			    size_t buflen);

       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 compares two network address objects; returning zero only
       if they are identical. The objects need not have 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 prints a 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 object.

       ne_iaddr_parse parses a string representation of a network address
       (such as "127.0.0.1" and creates a network address object to represent
       the parsed address.

       ne_iaddr_raw writes the raw byte representation of a network address to
       the provided buffer. The bytes are written in network byte order; the
       buffer must be of suitable length for the type of address (4 bytes for
       an IPv4 address, 16 bytes for an IPv6 address).

       ne_iaddr_reverse performs a reverse name lookup on the address object,
       writing the (first) hostname associated with the IP address to the
       provided buffer. If the hostname is longer than the buffer it will be
       silently truncated; on success the string written to the buffer is
       always NUL-terminated.

       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.

       ne_iaddr_parse returns a network address object on success, or NULL on
       failure to parse the address parameter.

       ne_iaddr_reverse returns zero on success or non-zero if no hostname is
       associated with the address.

       ne_iaddr_raw returns the buffer parameter, 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 {
	       /* ... */
	   }
