'GI.Gio.Objects.Resolver.Resolver' provides cancellable synchronous and asynchronous DNS
resolution, for hostnames ('GI.Gio.Objects.Resolver.resolverLookupByAddress',
'GI.Gio.Objects.Resolver.resolverLookupByName' and their async variants) and SRV
(service) records ('GI.Gio.Objects.Resolver.resolverLookupService').

'GI.Gio.Objects.NetworkAddress.NetworkAddress' and 'GI.Gio.Objects.NetworkService.NetworkService' provide wrappers around
'GI.Gio.Objects.Resolver.Resolver' functionality that also implement 'GI.Gio.Interfaces.SocketConnectable.SocketConnectable',
making it easy to connect to a remote host\/service.

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 'GI.Gio.Objects.InetAddress.inetAddressNewFromString').

On success, 'GI.Gio.Objects.Resolver.resolverLookupByName' will return a non-empty 'GI.GLib.Structs.List.List' of
'GI.Gio.Objects.InetAddress.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. 'GI.Gio.Objects.SocketListener.socketListenerAddAddress'.

If the DNS resolution fails, /@error@/ (if non-'Nothing') will be set to a
value from 'GI.Gio.Enums.ResolverError' and 'Nothing' will be returned.

If /@cancellable@/ is non-'Nothing', it can be used to cancel the
operation, in which case /@error@/ (if non-'Nothing') will be set to
'GI.Gio.Enums.IOErrorEnumCancelled'.

If you are planning to connect to a socket on the resolved IP
address, it may be easier to create a 'GI.Gio.Objects.NetworkAddress.NetworkAddress' and use its
'GI.Gio.Interfaces.SocketConnectable.SocketConnectable' interface.

Synchronously performs a DNS SRV lookup for the given /@service@/ and
/@protocol@/ in the given /@domain@/ and returns an array of 'GI.Gio.Structs.SrvTarget.SrvTarget'.
/@domain@/ may be an ASCII-only or UTF-8 hostname. Note also that the
/@service@/ and /@protocol@/ arguments do not include the leading underscore
that appears in the actual DNS entry.

On success, 'GI.Gio.Objects.Resolver.resolverLookupService' will return a non-empty 'GI.GLib.Structs.List.List' of
'GI.Gio.Structs.SrvTarget.SrvTarget', sorted in order of preference. (That is, you should
attempt to connect to the first target first, then the second if
the first fails, etc.)

If the DNS resolution fails, /@error@/ (if non-'Nothing') will be set to
a value from 'GI.Gio.Enums.ResolverError' and 'Nothing' will be returned.

If /@cancellable@/ is non-'Nothing', it can be used to cancel the
operation, in which case /@error@/ (if non-'Nothing') will be set to
'GI.Gio.Enums.IOErrorEnumCancelled'.

If you are planning to connect to the service, it is usually easier
to create a 'GI.Gio.Objects.NetworkService.NetworkService' and use its 'GI.Gio.Interfaces.SocketConnectable.SocketConnectable'
interface.

implements its own cache policies on top of that, and then set
itself as the default resolver for all later code to use.
