How to wait all data to be sent on stream before main thread end program

[ami-GS]

Some application just send data once then quickly close by design. and launched by cron etc.
How can the app over quic wait all the data on stream to be sent?
Even if the app call *Shutdown(), these are non-blocking functions, app could finish before the data sent.

There are a couple ways you might achieve this, but all of them rely on either explicitly or implicitly waiting on the "shutdown complete" event before closing the object(s). The simplest way for a fire-and-forget style protocol would be to so something like the sample. You will notice the RunClient simply starts the connection async and then returns, eventually calling RegistrationClose. The start will asynchronously kick off other work, like opening and sending stream data. The main thread that calls RegistrationClose will block (wait) until the connection has been closed; so as long as the code cleans up asynchronously, correctly, eventually everything completes nicely and then returns/exits.

Thanks! I did not notice the blocking call!
