ne_addr_resolve 3 ne_addr_resolve ne_addr_result ne_addr_first ne_addr_next 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 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 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. ne_addr_resolve returns a pointer to an address object, and never &null;. ne_addr_error returns the buffer parameter . 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);
