gResolverLookupService
will return a list
of
GSrvTarget
, 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-NULL
) will be set to
a value from GResolverError
.
If cancellable
is non-NULL
, it can be used to cancel the
operation, in which case error
(if non-NULL
) will be set to
G_IO_ERROR_CANCELLED
.
If you are planning to connect to the service, it is usually easier
to create a GNetworkService
and use its GSocketConnectable
interface.
