NAME

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

SYNOPSIS

       #include <ne_socket.h>

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

       int ne_addr_result(const ne_sock_addr *addr);

       const ne_inet_addr *ne_addr_first(ne_sock_addr *addr);

       const ne_inet_addr *ne_addr_next(ne_sock_addr *addr);

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

       void ne_addr_destroy(ne_sock_addr *addr);

DESCRIPTION

       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 must 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.  "192.0.34.72"); or, on systems which support IPv6, an IPv6 hex
       address, 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_addr_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
       returns 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.

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

RETURN VALUE

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

EXAMPLES

       The code below prints out the set of addresses associated with the hostname
       www.google.com.

           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 {
               const ne_inet_addr *ia;
               printf("www.google.com:");
               for (ia = ne_addr_first(addr); ia != NULL; ia = ne_addr_next(addr)) {
                   printf(" %s", ne_iaddr_print(ia, buf, sizeof buf));
               }
               putchar('\n');
           }
           ne_addr_destroy(addr);
