Handle connection lost while data is being sent (C++)

[Rohan Chawhan]

Hi all, I want to display a "user defined error" whenever the client-server connection is lost. I reached this blog where a similar issue is shown by printing log. I want to first include this minimum functionality in my client to get notified as soon as the client-to-server connection is broken/unreachable (due to any possible reason).

I could not find any informative resource on this topic for C++. can someone help to handle this connection lost scenario?

Hi,

The below may be useful.

Check channel.GetState() method to check the latest state of channel.

https://github.com/grpc/grpc/blob/master/doc/connectivity-semantics-and-api.md

Check below method as well but it is blocking call.

bool WaitForStateChange(grpc_connectivity_state source_state, gpr_timespec deadline);
