neon 0.34.2                                       15 April 2025                               NE_ADDR_RESOLVE(3)

       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.

       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);

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

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