Hi,
You would need to call WaitForStateChange to wait for the connectivity
state to actually change. A sample way to do this would be -
while ((state = channel->GetState(/*try_to_connect=*/true)) !=
GRPC_CHANNEL_READY) {
if (!channel->WaitForStateChange(state, deadline)) {
// deadline has expired
}
}
