NE_ADDR_RESOLVE(3)			neon API reference		       NE_ADDR_RESOLVE(3)

       ne_addr_resolve,     ne_addr_result,	ne_addr_first,	  ne_addr_next,    ne_addr_print,
       ne_addr_error, ne_addr_destroy - functions to resolve hostnames to addresses

       #include <ne_socket.h>

       ne_sock_addr *ne_addr_resolve (const char *hostname, int flags);

       int ne_addr_result (const ne_sock_addr *addr);

       ne_inet_addr *ne_addr_first (ne_sock_addr *addr);

       ne_inet_addr *ne_addr_next (ne_sock_addr *addr);

       char *ne_addr_print (const ne_inet_addr *iaddr, char *buffer, size_t bufsiz);

       char *ne_addr_error (const ne_sock_addr *addr, char *buffer, size_t bufsiz);

       void ne_addr_destroy (ne_sock_addr *addr);

       The ne_addr_resolve function resolves the given hostname, returning an ne_sock_addr object
       representing  the address (or addresses) associated with the hostname. The flags parameter
       is currently unused, and should be passed as 0.

       The hostname passed to ne_addr_resolve can be a DNS hostname (e.g. www.example.com) or  an
       IPv4  dotted  quad  (e.g.; or, on systems which support IPv6, an IPv6 hex ad-
       dress, which may be enclosed in brackets, e.g. [::1].

       To determine whether the hostname was successfully resolved, the  ne_addr_result  function
       is  used,  which  returns non-zero if an error occurred. If an error did occur, the ne_ad-
       dr_error function can be used, which will copy the error string into a  given  buffer  (of
       size bufsiz.

       The  functions  ne_addr_first and ne_addr_next are used to retrieve the Internet addresses
       associated with an address object which has been successfully resolved. ne_addr_first  re-
       turns  the first address; ne_addr_next returns the next address after the most recent call
       to ne_addr_next or ne_addr_first, or NULL if there are no more addresses. The ne_inet_addr
       pointer returned by these functions can be passed to ne_sock_connect to connect a socket.

       To  return  the	string	representation of a particular network address, the ne_addr_print
       function can be used.

       After the address object has been used, it should be destroyed using ne_addr_destroy.

       ne_addr_resolve returns a pointer to an address object, and never NULL. ne_addr_error  and
       ne_addr_print both return the buffer parameter .

       The   code   below   prints  out  the  set  of  addresses  associated  with  the  hostname

       ne_sock_addr *addr;
       char buf[256];

       addr = ne_addr_resolve("www.google.com", 0);
       if (ne_addr_result(addr)) {
	   printf("Could not resolve www.google.com: %s\n",
		  ne_addr_error(addr, buf, sizeof buf));
       } else {
	   ne_inet_addr *ia;
	   for (ia = ne_addr_first(addr); ia != NULL; ia = ne_addr_next(addr)) {
	       printf(" %s", ne_addr_print(ia, buf, sizeof buf));
