Function Documentation

grpc_connectivity_state grpc_channel_check_connectivity_state	(	grpc_channel *	channel,
		int	try_to_connect
	)

Check the connectivity state of a channel.

void grpc_channel_watch_connectivity_state	(	grpc_channel *	channel,
		grpc_connectivity_state	last_observed_state,
		gpr_timespec	deadline,
		grpc_completion_queue *	cq,
		void *	tag
	)

Watch for a change in connectivity state.

Once the channel connectivity state is different from last_observed_state, tag will be enqueued on cq with success=1. If deadline expires BEFORE the state is changed, tag will be enqueued on cq with success=0.
