Resolver.lookupByNameWithFlagsAsync

void lookupByNameWithFlagsAsync(string hostname,  gio.types.ResolverNameLookupFlags flags,  gio.cancellable.Cancellable cancellable =  null,  gio.types.AsyncReadyCallback callback =  null)

Begins asynchronously resolving hostname to determine its associated IP address(es), and eventually calls callback, which must call gio.resolver.Resolver.lookupByNameWithFlagsFinish to get the result. See gio.resolver.Resolver.lookupByName for more details.

Parameters

`hostname`	the hostname to look up the address of
`flags`	extra #GResolverNameLookupFlags for the lookup
`cancellable`	a #GCancellable, or null
`callback`	callback to call after resolution completes
