void grpc_resolver_channel_saw_error	(	grpc_resolver *	resolver,
		struct sockaddr *	failing_address,
		int	failing_address_len
	)

Notification that the channel has seen an error on some address.

Can be used as a hint that re-resolution is desirable soon.

void grpc_resolver_init	(	grpc_resolver *	resolver,
		const grpc_resolver_vtable *	vtable
	)

void grpc_resolver_next	(	grpc_resolver *	resolver,
		grpc_client_config **	target_config,
		grpc_iomgr_closure *	on_complete
	)

Get the next client config.

Called by the channel to fetch a new configuration. Expected to set *target_config with a new configuration, and then schedule on_complete for execution.

If resolution is fatally broken, set *target_config to NULL and schedule on_complete.
