async grpc CQ loop

[Rajmohan Banavi]

Have a single threaded grpc streaming server which alternately checks for events on queue (AsyncNext) and other network events (using select with timeout). On receiving a socket network event, the server needs to send a grpc reply to the client. To send a grpc reply upon receiving some data on socket, how can one get the tag? Any suggestions/pointers appreciated.

Another method suggested is to run select in a separate thread. Any pointers or sample code that I can look at?

Thanks.

The tag is something (any void pointer) you pass to the API when starting an operation like read or write. The tag in-a-way is the Identifier for the operation you started. AsyncNext just returns the tag that you passed to indicate that the operation completed.

For more details, please see the grpc example at:
