how to reject a new peer stream

[fofewyoung]

case QUIC_CONNECTION_EVENT_PEER_STREAM_STARTED:
            {
                     //  no SetCallbackHandler

                     // close here
                    MsQuic->StreamClose(Event->PEER_STREAM_STARTED.Stream);

                    // return success?
                    return QUIC_STATUS_SUCCESS;
            }

is it correct?

You should explicitly shutdown (abort) the stream with an app-specific error code so the peer know why you did it. If you just call close, the stack defaults to error 0, which might not be what you want.

in my case, the error code is not important.
i expect it should be closed as soon as possible.

In fact, I want to do this because I'm afraid that aggressive clients will create a large number of streams, which will cause the server memory to crash; So I want to limit the number of streams created

Maybe, you can use the setting, peerBidiStreamCount, to limit the stream count.

Yes, ideally, you should only configure the number of streams you're willing to accept at a time. That way, you don't need to reject anything because they can't even send too many to begin with.
