Asynchronous and cancellable DNS resolver.
Resolver provides cancellable synchronous and asynchronous DNS resolution, for hostnames (lookup_by_address(), lookup_by_name() and their async variants) and SRV (service) records (lookup_service()).
NetworkAddress and NetworkService provide wrappers around Resolver functionality that also implement SocketConnectable, making it easy to connect to a remote host/service.

Glib::ustring Gio::Resolver::lookup_by_address | ( | const Glib::RefPtr< InetAddress > & | address | ) |

Glib::ustring Gio::Resolver::lookup_by_address | ( | const Glib::RefPtr< InetAddress > & | address, |
const Glib::RefPtr< Cancellable > & | cancellable | ||
) |
Synchronously reverse-resolves address to determine its associated hostname.
If the DNS resolution fails, error (if non-nullptr
) will be set to a value from ResolverError.
If cancellable is non-nullptr
, it can be used to cancel the operation, in which case error (if non-nullptr
) will be set to Gio::Error::CANCELLED.

void Gio::Resolver::lookup_by_address_async | ( | const Glib::RefPtr< InetAddress > & | address, |

address | The address to reverse-resolve. |
slot | A callback slot to call after the resolution completes. |

Retrieves the result of a previous call to g_resolver_lookup_by_address_async().

std::vector< Glib::RefPtr< InetAddress > > Gio::Resolver::lookup_by_name | ( | const Glib::ustring & | hostname | ) |
A lookup_by_name() convenience overload.
std::vector< Glib::RefPtr< InetAddress > > Gio::Resolver::lookup_by_name | ( | const Glib::ustring & | hostname, |
const Glib::RefPtr< Cancellable > & | cancellable | ||
) |
Synchronously resolves hostname to determine its associated IP address(es).
hostname may be an ASCII-only or UTF-8 hostname, or the textual form of an IP address (in which case this just becomes a wrapper around g_inet_address_new_from_string()).
On success, g_resolver_lookup_by_name() will return a non-empty List of InetAddress, sorted in order of preference and guaranteed to not contain duplicates. That is, if using the result to connect to hostname, you should attempt to connect to the first address first, then the second if the first fails, etc. If you are using the result to listen on a socket, it is appropriate to add each result using e.g. g_socket_listener_add_address().
If the DNS resolution fails, error (if non-nullptr
) will be set to a value from ResolverError and nullptr
will be returned.
If cancellable is non-nullptr
, it can be used to cancel the operation, in which case error (if non-nullptr
) will be set to Gio::Error::CANCELLED.
If you are planning to connect to a socket on the resolved IP address, it may be easier to create a NetworkAddress and use its SocketConnectable interface.
hostname | The hostname to look up. |
cancellable | A Cancellable, or nullptr . |
nullptr
